Introduction

Congratulations on your purchase of the E-MU Proteus 2000 – the composer’s dream machine. The power of Proteus 2000 begins with 128 voice polyphony, which means that 128 different instrument lines can be played at once! With all these voices, 16 MIDI channels didn’t seem to be quite enough, so we added another MIDI input jack to allow 32 MIDI channel operation. As long as we were going for the gold, we decided to add the ability to access 128MB of sound memory on user upgradable SIMMs. And there’s much more as you will soon discover.

Product Description

Proteus 2000 contains four user-upgradable sound SIMM sockets, allowing you to mix and match sound sets according to your needs. New sounds can be added as easily as plugging in a new 16MB or 32MB SIMM module and up to 128MB of sounds can be added! Each sound set has been meticulously crafted to be the best of its kind. Samples are matched across the keyboard, perfectly looped, and rich in harmonic texture.

Proteus contains 512 user presets and can hold literally thousands of factory presets. (ROM presets are automatically added when sound SIMMs are

installed. As an example, a 32 MB SIMM may contain up to 1024 ROM presets.)

Proteus 2000’s Sound Navigator is a major improvement to the main screen that makes it easy to ﬁnd the exact sound you want from the thousands available. It’s powerful, yet simple to use.

Of course the real power of Proteus 2000 becomes apparent when you synthesize your own sounds. The extremely ﬂexible yet easy to use, 4-layer synthesizer voices make it easy to build sounds of any kind. Layers can be switched or crossfaded using key position, velocity, real-time controllers or any modulation source. Proteus 2000 also contains 50 different types of 2nd to 6th order resonant & modeling ﬁlters which are used to shape and modify the raw waveforms.

The 64 modulation sources include three multistage envelopes and two LFOs per layer, as well as full MIDI control over virtually every parameter. The digital patch bay, with 24 cords per layer, (and 12 more cords per preset) lets you connect modulation sources to 64 destinations in any imaginable way.

Proteus 2000 Operation Manual 1

Introduction Overview

The patch bay contains a set of arithmetic modiﬁers, letting you create complex synthesis models.

Four front panel real-time controllers give you control over 12 userselectable parameters. The real-time knobs can adjust multiple synthesizer functions at once, allowing complex levels of control. For example, one knob can simultaneously turn up ﬁlter cutoff, while detuning one sample, and adjusting the release time of the volume envelope. Virtually every synth parameter in the Proteus 2000 is controllable using the real-time knobs or by any internal or external control source.

Six 20-bit analog outputs let you process separate sounds and integral effect sends externally. Returns allow the addition of external effects units without the need for a separate mixer.

Once you have created your preset, you can add richness to your sound using Proteus 2000’s 24-bit stereo effects. You can choose a different effects setup for each preset from over 60 algorithms. Proteus 2000’s effects section is actually two separate effects processors with control over each wet/dry mix level. Effects Processor “A” contains primarily ambiance algorithms like reverb and delays, while effects processor “B” contains primarily spectral algorithms such as chorus, ﬂange, phase, distortion, and delay. Effects can be linked to each preset or used globally to further enhance your sound.

Overview

The S/PDIF digital stereo output lets you connect to other digital equipment, such as digital mixers or external effects devices, keeping your signal entirely in the digital domain.

Other features include multiple solo, voice assignment and performance modes for expressive control, 12 user-deﬁnable alternate tunings, an extremely easy to use interface and, of course, an extensive MIDI implementation.

This is the Operations Manual for setting up and playing Proteus 2000. The ﬁrst part of the manual describes how to unpack and setup the hardware.

The next chapters provide step-by-step instructions for the most common and widely used features of Proteus 2000. This section also deﬁnes each of the parameters (by menu) and provides information on how to use them.

The appendix provides technical information, product speciﬁcations and the Index.

Proteus 2000 is controlled by MIDI messages received at the MIDI A jack. Normally you will connect MIDI Out of a controller such as a MIDI keyboard, MIDI wind controller or MIDI guitar controller to the MIDI A jack of Proteus 2000.

Outputs

Proteus 2000 is a high quality, stereo audio device. In order to reproduce its wide dynamic range and frequency response, use a high quality ampliﬁcation and speaker system such as a keyboard ampliﬁer or home stereo system. A stereo setup is highly desirable because of the added realism of stereophonic sound. Headphones can be used if an ampliﬁer and speaker system is not available. Plug stereo headphones into the headphone jack located on the left side of the front panel. The Right Main output jack serves as a mono output when the Left Main plug is not plugged in. The Left Main output jack is a stereo jack carrying both channels.

The S/PDIF output duplicates the function of the main output.

Proteus 2000 is controlled by MIDI messages received at either MIDI input. In a live performance situation, you might want to use two MIDI controllers as shown above. Connect MIDI outputs of your MIDI controllers such as a MIDI keyboard, MIDI drum pads or a MIDI sequencer to MIDI Inputs A and B of Proteus 2000.

MIDI Thru

The MIDI Thru jack is used to connect additional MIDI devices onto the MIDI chain. MIDI Thru transmits an exact copy of the messages received at the respective MIDI In jack (A or B).

Outputs

The Sub 1 and Sub 2 output jacks are stereo jacks. The tip of each jack (accessed when a standard phone plug is inserted) connects to the left or right output of that group. The S/PDIF output duplicates the function of the main output.

Setup

Connection Instructions

If you insert a stereo plug into one of the Sub Outputs, the ring of the plug serves as a signal Return which sums into the Main outputs.

Therefore, the Sub 1 and Sub 2 jacks can serve as effect sends and returns in order to further process selected instruments and then return them to the main mix.

You can use the Sub 1 and Sub 2 jacks as send/returns in order to further process selected Proteus 2000 presets without using the effects bus on the mixing board. In a pinch, the effect returns can be used to sum additional instruments into the main outputs. It’s like having an extra line mixer when you need more inputs!

You can select presets from the Preset Number, Bank Number, Preset Category or Preset Name ﬁelds.

Setup

Instant Gratiﬁcation

Each bank of 128 presets is identiﬁed by a superscripted Bank Number to the right of the preset number. The bank numbers reset to 0 at the start of each ROM card you have installed. So with the composer ROM installed, the User banks will go from 0-3, then start over from 0-7 for the CMPSR banks.

To the right of the preset number and bank is the preset Category name followed by the Preset Name.

 To Change the Preset

1. Place the cursor under the ﬁrst character in the Preset Number ﬁeld.

This is the “Home” position which is selected instantly when you press the Home/Enter button. Pressing either of the two cursor buttons repeatedly also gets you there.

2. Turn the Data Entry Control knob on the front panel to select a new

preset number. If you turn the knob slowly, the presets advance one number for each “click” of the knob. If you spin the knob quickly, the numbers advance much faster (more than one number per click).

3. Play the keyboard (or press the Audition button) and listen to the

sounds made by your Proteus 2000!

4. TURN THE FOUR KNOBS on the front panel and note how they

change the sound of each preset! The button to the left of the knobs changes the knob’s function. Don’t worry about ruining the sound, the values are automatically reset as soon as you select a new preset.

Front Panel The Proteus 2000 front panel contains an LCD screen, nine buttons and

four real-time controllers. Functions are grouped logically and the controls are arranged for ease of use. Precisely because Proteus is so simple to use, you might be tempted to skip this section. If you just can’t help yourself, at least read the Real-time Controller information beginning page 23. There are several “power user” features in the interface which make programming even easier and we wouldn’t want you to miss them.

Volume Control This control is the master volume control for all audio outputs. The Volume

Control does not affect any editing or user interface operations.

Master Button The Master menu contains parameters that affect the entire machine, not

just certain presets. An illuminated LED to the right of the button indicates that you are in the Master menu.

Edit Button Use the Edit menu when you want to create or modify a preset. An illumi-

nated LED to the right of the button indicates that you are in the Edit menu.

Control Button The Control button is used to change the function of the Controller knobs

(see the next section). Each time you press the Control button, the Control Mode toggles to select only one of the three Control Rows. The currently selected Control Row is indicated by one of the three LEDs to the right of the row’s label.

Multimenu Button The Multimenu button allows you to select a Multi-setup. A Multi-setup is a

group of parameters that you might associate with a particular sequence or song. It is like a “snapshot” of the current conﬁguration of the module. There are 128 setups numbered 0-127.

A Multisetup includes all of the following parameters:

• The Preset/Volume/Pan assignments for each of the 32 MIDI channels.

• All Master menu parameters, except for the User Tuning Tables and the

MIDI program change->preset map.

• The Multisetup name.

Save/Copy Button The Save/Copy button is used to save or copy presets and to copy data.

Selected groups of parameters, such as PatchCord settings, can be copied between Presets and/or between Layers using this menu.

The LED to the right of the button illuminates to indicate that you are in the Save/Copy menu. The LED also illuminates when any preset parameter has been changed in the Edit menu (or if the front panel knobs have been moved with Quick-Edit mode enabled).

22 E-MU Systems

Basic Operations

Front Panel Controller Modes

Home/Enter Button The Home/Enter button is dual purpose. In general, this button acts as the

“Home” button. For example, when in an Edit menu, this button snaps the cursor to the page name ﬁeld of the current screen. When viewing the Preset Select screen (we also call it the main screen), this button snaps the cursor to the preset number ﬁeld. In these instances, the LED is not used.

Some screens and parameter ﬁelds use this button as the “Enter” button. In these cases, the LED blinks when the cursor is moved to one of these ﬁelds indicating that the module is waiting for your response to initiate the operation.

Data Entry Control The Data Entry Control is a stepped, variable control switch used to change

parameter values. The wheel increments or decrements the current value one unit with each click. This control incorporates acceleration, which advances the value faster if the Data Entry Control is turned quickly.

Controller Knobs Each of the four Real-time Controller knobs has a corresponding LED to its

upper right side. The function of the Real-time Controllers depends on which row is currently selected and the programming of the preset.

Front Panel Controller Modes

The Real-time Controller Knobs serve three purposes:

1. Real-time control of synthesizer parameters

2. “Quick Editing” the initial settings of the real-time controllers

3. “Deep Editing” the parameters

This section describes each of the three uses.

Real-time Control The Real-time controller knobs provide direct control of the Proteus 2000’s

synthesizer parameters. They are always active when on the Preset Select (main) screen. They can optionally be used to transmit MIDI controller messages to other MIDI devices.

The Control button (left of the knobs) changes the function of the real-time controller knobs. Each time the button is pressed, the Control Mode toggles to select one of the three Control Row groups. The currently selected Control Row is indicated by the illuminated LED to the right of the button. The control knob functions are determined by the selected Control Row.

The three Control Rows generate MIDI data that can control the preset on the current MIDI channel (the channel showing on the Preset and main screen. The labels (Tone, Presence, Shape, Image, etc.) printed on these rows show how the factory ROM presets may be programmed to respond. (The controls might not conform to the front panel labels depending on the preset.) You can change the way a preset responds to MIDI A-L messages from the Edit menu (PatchCords).

Proteus 2000 Operation Manual 23

Basic Operations

Front Panel Controller Modes

There is an LED next to each of the control knobs which illuminates to indicate that the knob setting has been changed from the value programmed in the preset (when Quick Edit mode is enabled). If the knob position is returned to the original setting, the LED is extinguished.

If the “Knobs MIDI Out” parameter in the Master menu (see “Knobs/Riff MIDI Out” on page 49) is set to “transmit,” the system sends a MIDI controller message when you turn off the Control knob. The MIDI controller message is sent on the current MIDI channel (also called the basic channel) using the controller number assigned in the Master menu (see “Real-time Controller Assignment” on page 46).

The knobs only generate a message when you move a knob to a new value. The current value jumps to the new value.

Quick Edit This mode uses the Controller knobs to “Quick-Edit” the currently selected

preset without having to enter the Preset Edit menu. This mode is only active when on the Preset Select screen and when “Quick-Edit” is enabled in the Master menu (see “Knob Preset Quick-Edit” on page 48).

Quick-Edit mode must be enabled in the Master menu.

Initial controller values can be stored in every preset. When you move a knob with Quick-Edit enabled, the Initial Controller Value is updated with the knob’s new value. The knob’s LED lights indicating that the preset value has been changed. The three Control Rows’ MIDI A-L values are stored in the corresponding Initial Controller Amount parameter in the Edit menu (see “Initial Controller Amount” on page 125). The Save/Copy button LED illuminates to remind you that the preset has been edited. “Quick-Edits” made to a preset are lost if you select another preset before saving them.

 To Quick-Edit a Preset

1. Use the Control Knobs to change the sound of the current preset as

desired.

2. Press the Save/Copy button. The display reads, “Save Preset to.”

3. Press the right cursor button to select the bottom row.

4. Optional: Select a new preset location if you don’t want to overwrite

the current preset, or if the current preset is a ROM preset.

5. Press the Enter button to save the preset.

Multitimbral Sequencing

“Multitimbral” means that Proteus 2000 can play multiple sounds at the same time. For a multitimbral sequence to play back correctly, the proper preset must be selected for each MIDI channel. This could be done by inserting preset changes into each track of your sequence before the sequence starts. Proteus 2000 also provides another way to store this “presequence setup” using the Multisetup menu.

Using Multisetups, you’ll set up the preset, volume and pan settings for each MIDI channel as you build your sequence, then save the Multisetup when it’s the way you want it. Sending one preset change command before the sequence starts selects the Multisetup and MIDI settings for all 32 channels.

 To Set up Proteus 2000 for Multitimbral Operation

1. Set the MIDI mode to “multi mode,” using the MIDI mode function in

the Master menu.

2. Decide which MIDI channels you want Proteus 2000 to receive (32

channels can be used simultaneously). If you are using 16 MIDI channels or less, just use one of the MIDI ports. Use both MIDI ports if you need more than 16 MIDI channels. You can turn any unused channels OFF using the MIDI Enable function in the Master menu.

3. Select the desired preset for each of the MIDI channels you want the

Proteus 2000 to receive using the MIDI Channel/Preset selection screen. You can also set the initial Volume and Pan settings for each channel.

Parameters

Transpose/Tune The Transpose parameter transposes the key of all presets, in semitone

intervals. The transpose range is ± 24 semitones. Master Tune adjusts the ﬁne tuning of all presets so that you can tune

Proteus 2000 to other instruments. The master tuning range is ± 1 semitone in 1/64th semitone increments (1.56 cents). A master tune setting of “+00” indicates that Proteus 2000 is perfectly tuned to concert pitch (A=440 Hz).

Mix Output The Mix Output parameter allows you to override the routing assignments

made in each preset and instead assign the outputs according to MIDI channel. For each of the 32 MIDI channels, you can select Send 1-4, or Preset. When Preset is selected, the output assignment deﬁned in the Preset Edit menu is used.

MIX OUTPUT

channel 16A: Send2->main

Indicates that the dry signal is

routed to the Main output jacks.

The Output Routing ﬁeld (pointed to by the arrow) reﬂects the true routing of Send 2 or Send 3 to either:

1) the effects processor input or… 2) the rear panel submix jacks.

Since the Sub 1 output is NOT being used, the signal is routed through the effects processors, then on to the main outputs. If a plug were inserted into one of the Sub 1 jacks the destination ﬁeld would read “Sub1” and the dry signal would be routed directly to the Sub 1 outputs on the back panel.

MIX OUTPUT

The Sends function as effect processor inputs (effect sends). Send 2 and Send 3 are also used to route sounds to the Sub 1 and 2 outputs on the back panel. When a plug is inserted into the associated Submix jack on the back panel, the Dry portion of the Send is disconnected from the effects processor and the signal is routed directly to the output jack. The actual output routing is shown in parentheses in the display. If you don’t want the wet portion of the signal in the main mix, turn down the Send Level.

The entire Send is disconnected from the Effects Processors even if only one plug is inserted into the Submix jack.

The four Effect Sends allow you to get the most out of the two effect processors. For example, with Effect B set to an echo algorithm, you could route one MIDI channel to Send 3 and set the effect amount to 80%. Another MIDI channel could be routed to Send 4 with an effect amount of only 5%. This is almost like having two different effects!

The Mix Output function is also useful when sequencing since it lets you route speciﬁc MIDI channels (and thus sequencer tracks) to speciﬁc Sub outputs (on the back panel) where there they can be processed with EQ or other outboard effects.

The Master Effects settings assign the effect processors “globally” for all presets to provide a way to use the effects in Multi mode. Detailed information is presented in the Effects chapter (see Effects on page 143).

For example, assigning a MIDI controller to “A” in this screen would let you control ﬁlter Fc for all the factory presets. See “Front Panel Knob Functions” on page 165.

Tempo Controller This function allows a MIDI controller to change the Master Tempo. The

Global Tempo is used for the clock divisor PatchCords, tempo-based envelopes and synced LFOs. You can assign any controller number from 0-31, mono key pressure, or the pitch wheel to change the Global Tempo. A different controller can be used to change the tempo up or down. The Pitch Wheel can be assigned to both the up and down parameters to vary the tempo up and down from a single controller. If any other controller is assigned to both the up and down parameters, Proteus 2000 redeﬁnes the center of the controller’s range as zero.

MIDI Controller values are added to the Base Tempo with an offset range of ±64. When the controller is set to “off” the tempo returns to its original setting. This control has no effect when using an external clock.

MIDI SysEx Packet Delay

Send MIDI System Exclusive Data

Sometimes errors occur if the computer or sequencer to which you are sending MIDI SysEx data is faster or slower than the Proteus 2000. The MIDI SysEx Packet Delay command lets you specify the amount of delay between MIDI SysEx packets so the input buffer of your computer does not overﬂow, causing an error. The value range is from 0 through 8000 milliseconds. A delay value of zero allows full speed MIDI transfer. If you are experiencing data transmission errors, try increasing the delay value until the problem disappears.

MIDI SYSEX PACKET DELAY

300 milliseconds

This command transmits MIDI System Exclusive (SysEx) data to the MIDI Out port of Proteus 2000. The MIDI data can be sent to a computer, sequencer or to another Proteus 2000. When transferring data between two Proteus 2000s be sure both units have the same SysEx ID number! See “MIDI SysEx ID” on page 44 to learn how to change the SysEx ID.

Base Tempo Proteus 2000 contains an internal master clock which can be used to:

synchronize the LFOs when in Tempo-based mode, control the times of Tempo-based envelopes or used as a modulation source in the PatchCords section. There are two tempo values shown in the display.

• Base Tempo - The base tempo is the value to which the MIDI controller speciﬁed in the Tempo Controller screen will be applied. (See “Tempo Controller” on page 48.)

• Current Tempo - The current tempo is equal to the base tempo modu- lated by the MIDI controller speciﬁed in the Tempo Controller screen. If no MIDI Tempo controller message has been received since the last Base Tempo change, the Current Tempo will be equal to the Base Tempo.

Current Tempo is NOT displayed when the Base Tempo is set to “MIDI Clock”.

Programming Basics

This chapter explains how Proteus 2000 sounds are constructed and contains important background information on how to create your own custom presets.

Your initial involvement with Proteus 2000 will most likely be using the existing presets and selecting MIDI channels. While the factory presets are very good, there are some things you will probably want to change eventually, perhaps the LFO speed, the ﬁlter frequency or the attack time. You may also want to make your own custom presets using complex modulation routings. There are 512 user locations (User Banks 0-3) available to store your own creations or edited factory presets. Best of all, it’s easy to edit or create new presets using the Edit menu.

Each preset can consist of up to four instrument layers. Each of the four layers can be placed anywhere on the keyboard and can be crossfaded or switched according to key position, velocity, or by using a real-time control such as a wheel, slider, pedal, LFO or envelope generator. A preset can also be “linked” with up to 2 more presets creating additional layering or splits.

Proteus 2000 has an extensive modulation implementation using two multi-wave LFO’s (Low Frequency Oscillators), three multi-stage envelope generators and the ability to respond to multiple MIDI controllers. You can simultaneously route any combination of these control sources to multiple destinations.

Proteus 2000 Operation Manual 55

Programming Basics

Modulation

Modulation To modulate means to dynamically change a parameter, whether it be the

volume (amplitude modulation), the pitch (frequency modulation), and so on. Turning the volume control on your home stereo rapidly back and forth is an example of amplitude modulation. To modulate something we need a modulation source and a modulation destination. In this case, the source is your hand turning the knob, and the destination is the volume control. If we had a device that could turn the volume control automatically, we would call that device a modulation source.

Turning the volume control back and forth on your home stereo is an example of Amplitude Modulation.

Proteus 2000 is designed so that each of the variable parameters, such as the volume, has an initial setting which is changed by a modulation source. Therefore in the case of volume, we have an initial volume that we can change or modulate with a modulation source.

Two main kinds of modulation sources on Proteus 2000 are Envelope Generators and Low Frequency Oscillators. In the example above, an envelope generator could be routed to automatically turn the volume control as programmed by the envelope. Or, a low frequency oscillator could be routed to turn the volume up and down in a repeating fashion.

Positive modulation adds to the initial amount. Negative modulation subtracts from the initial amount.

Summing Nodes

All the modulation inputs on Proteus 2000 are summing nodes. This means that you can connect as many modulation sources as you want to an input (such as Pitch or AmpVol). Modulation sources are simply added algebraically— connecting two knobs, one set to -100 and the other set to +100 yields a net value of zero.

Tip: Try routing Key

Glide to Filter Frequency if you want the ﬁlter to smoothly follow pitch in solo mode. Routing Key Glide to Pan creates another interesting effect.

Modulation sources include Envelope Generators, Performance Controllers and Low Frequency Oscillators. In the previous example, an envelope generator

was routed to automatically turn the volume control as programmed by the envelope, or, a low frequency oscillator could be routed to turn the volume control up and down in a repeating fashion. The following is a list of the modulation sources used in Proteus 2000.

Programming Basics

Modulation PatchCords

Random Sources Random modulation sources can be used when you want the timbre of the

sound to be “animated” in a random or non-consistent manner.

• Key Random 1 & 2 generate different random values for each layer which do not change during the note.

• The White & Pink Noise Generators produce varying random values. Both white and pink noise sources are low frequency noise designed for control purposes. Either noise source can be ﬁltered even more by passing it through a lag processor.

• The Crossfade Random function generates the same random value for all layers in a preset. This source is designed to be used for crossfading and cross-switching layers, although you may ﬁnd other uses.

Modulation PatchCords



The controller Knobs assignments printed on the front panel are the system defaults. You can change any of these assignments using the Real-time Controller Assignment page in the Master menu (see page 46 for details).

When setting up modulation with the Proteus 2000, you deﬁne a modulation source and a modulation destination. Then, you connect the source to the destination using “PatchCords.” Proteus 2000’s PatchCords are connected in the software. Proteus 2000 has 24 general purpose PatchCords for each layer.

You can connect the modulation sources in almost any possible way to the modulation destinations. You can even modulate other modulators. Each PatchCord also has an amount parameter which determines “how much” modulation is applied to the destination. The modulation amount can be positive or negative. Negative values invert the modulation source.

Programming Basics

Envelope Generators

If two adjacent segments have the same level in a “time-based” envelope, the segment will be skipped. Adjacent segments must have different levels for the rate control to work.

An envelope can be described as a “contour” which is used to shape the sound over time in a pre-programmed manner. There are three envelope generators per layer and all of them are the rate/level type.

This is how the rate/level (time based) envelopes work: When a key is pressed, envelope starts from zero and moves toward the Attack 1 Level at the Attack 1 Rate. As soon as it reaches this ﬁrst level, it immediately begins the next phase and moves toward the Attack 2 level at the Attack 2 rate. As long as the key is held down, the envelope continues on through the Decay 1 and Decay 2 stages. If the key is still held when the envelope reaches the end of Decay 2, it simply waits there for you to release the key. When you release the key, the envelope continues into the Release 1 and Release 2 stages, stopping at the end of the Release 2 stage. Proteus 2000’s envelope generators provide great ﬂexibility for programming both complex and simple envelopes.

All three envelope generators have the six stages described above. The Volume Envelope generator controls the volume of the voice over time. The Filter Envelope generator is a general purpose envelope most often used to control the ﬁlter frequency. Unlike the Volume Envelope, however, the Filter Envelope can have a negative level value as well as a positive level. There is also an Auxiliary Envelope generator which is a general purpose envelope. The Auxiliary Envelope is identical to the Filter Envelope and can have negative as well as positive levels. You can adjust the time of each stage to create myriad envelope shapes, which in turn shape the sound over time.

• Volume envelopes contour the way the volume of a sound changes over time determining how we perceive that sound. For example, a bell struck with a hammer is instantly at full volume, then slowly dies away. A bowed violin sound fades in more slowly and dies away slowly. Using Proteus 2000’s Volume Envelope, you can simulate the different types of natural instrument volume envelopes by programming them appropriately.

Tempo-based envelopes are based on Time which is controlled by the Master Tempo (located in the Master menu). The Master Tempo rate scales the time of the Tempo-based envelope segments.

The diagram above show how the looping envelopes work. When the key is pressed the envelope goes through its regular Attack 1, Attack 2, Decay 1 and Decay 2 stages. In non-looping mode, the envelope would hold at the end of the Decay 2 stage until the key was released. In looping mode however, it jumps back to the Attack 1 stage and repeats the ﬁrst four stages. It continues to loop through these four stages until the key is released where it immediately jumps to the Release 1 stage.

Low Frequency Oscillators (LFOs)

LFO Tricks & Tips:

• The Random LFO wave is truly random and is different for each voice and layer.

• The Pattern (Pat) waveforms will sound the same on different layers and voices.

• Sine + Noise is very useful for simulating trumpet and ﬂute vibrato.



Try combining the Pattern LFOs, or controlling the amount of one with another, or combining them with the clock divisors.

By examining the diagram of the LFO waveforms, you can see how an LFO affects a modulation destination. The shape of the waveform determines the result. Suppose we are modulating the pitch of an instrument. The sine wave looks smooth, and changes the pitch smoothly. The square wave changes abruptly and abruptly changes from one pitch to another. The sawtooth wave increases smoothly, then changes back abruptly. The sound’s pitch follows the same course. Controlling the pitch of an instrument is an easy way to hear the effects of the LFO waves.

Like the Auxiliary Envelope, LFOs can be routed to control any real-time function such as Pitch, Filter, Panning, or Volume. A common use for the LFO is to control the pitch of the sound (LFO -> Pitch). This effect is called vibrato and is an important performance effect. Many presets use this routing with the modulation wheel controlling “how much” LFO modulation is applied. Another common effect, Tremolo, is created by controlling the volume of a sound with the LFO (LFO -> Volume).

Proteus 2000 Operation Manual 61

Programming Basics

Clock Modulation

You might use the LFOs to add a slight bit of animation to the sound by routing the LFO to control the ﬁlter. For this effect, set the LFO “amount” low for a subtle effect.

When a PatchCord amount is a negative value, the LFO shape is inverted. For example, inverting the sawtooth wave produces a wave that increases abruptly, then smoothly glides down.

Negative Amount

Clock Modulation



Envelopes are triggered on the positive going edge of the clock. LFOs are triggered on the negative going edge of the clock.



The tempo of the master clock is set in the Master menu.

Sawtooth

You can use the Master Clock as a modulation source, to trigger the Filter or Auxiliary Envelope generators, trigger Sample Start, synchronize the LFOs, or directly as a square wave modulation source. The Clock source is available in eight divisions (octal whole note, quad whole note, double whole note, whole note, half note, quarter note, eighth note, sixteenth note). You can use the different rates separately or in conjunction to create complex “synchro-sonic” rhythm patterns. You can also use a MIDI Clock as the Master Clock to synchronize to an external MIDI device such as a drum machine or sequencer. (See Master Tempo in the Master menu.)

Clocks are routed exactly like the other modulations sources using the PatchCords. The PatchCord Amount MUST be positive (+) for the clock to pass. By modulating the PatchCord Amount, you can route the divided clocks using real-time controllers or other modulation sources.

When an LFO is triggered by a clock, the LFO wave resets to zero every time the clock wave goes low. If the LFO rate is close to the clock rate, the LFO virtually synchronizes with the clock. If the two rates are far apart, the waveform of the LFO will be mildly or radically altered.

Clock Modulation

LFOs can also be perfectly synchronized with the clock at any of 25 note divisions. This allows you to create very cool “synchro-sonic” effects that work perfectly at any tempo. Choosing one of the note divisors in the LFO rate screen selects the synced LFO function.

There are many possibilities for clock modulation and retrigger. For

example, you can create a repeating six segment curve of any shape by triggering the Filter or Auxiliary Envelope generators with the clock. A few other possibilities are listed below.

LFO Synced to 1/4 Note Clock

• Turn different voice layers on and off using different clock divisors.

• Switch between Auxiliary and Filter Envelope retriggering using a

slider or footswitch.

• Retrigger LFOs or Envelopes using noise or other LFOs to create random or semi random effects.

• Alter the LFO waveform by modulating the rate of a triggered LFO.

• Route multiple clocks with different divisors to the same destination

(such as pitch) to create complex patterns. (Hint: Adjust the PatchCord Amounts.)

Preset Modulation Processors

Preset Modulation

Processors start working as soon as the preset is selected. The Layer Modulation Processors take effect only when a key is pressed.

There are also two “Preset Level” modulation processors located in the “Preset Patchcords” screen of the Edit menu. It is important to understand that although the preset processors originate at the Preset Level PatchCords, their output is used in the Layer PatchCords.

Preset Lag

Like the Layer Lag processors (described on page 65) the Preset Lag slows down rapid changes in the input signal. The output “lags” behind the input at a pre-programmed rate. Unlike the layer level lag processors, the preset lag takes effect as soon as the preset is selected. In contrast, the layer level lag processors begin acting only after a keyboard key has been depressed. The Preset Lag also has a Lag Amount input which controls the lag time. Positive lag amounts increase the lag time. A MIDI controller (such as a front panel knob) is commonly used to control lag amount.

The preset lag could be used to “spin-up” and “spin-down” an LFO, which is controlling some other effect, perhaps left/right panning, pitch, or the ﬁlter. A MIDI footswitch could be used as the input to the lag which acts to slow down the instantaneous change of the switch. The slowly changing output value is then routed using a layer patchcord to crossfade between layers or change the speed of an LFO.

The preset ramp instantly resets when all notes have been released and the next ﬁrst key on the MIDI channel is pressed. The Ramp Rate polarity (+ or -) determines if the ramp will be positive or negative going. The value of the ramp rate sets the increment. Large values produce fast ramps and small values produce slow ramps. Multiple inputs can be connected to the ramp rate (just like all the other destinations in Proteus 2000).

The patch below shows an application for the Preset Ramp which generates an adjustable decay envelope ONLY on the ﬁrst note played to bring in the sound from another layer. Instead of routing the output to the Amp Volume you could just as easily route it to control Pitch, LFO Speed or any other destination you can think of.

Preset Modulation Processors

Using the Modulation Processors

Modulation processors are inserted into a modulation routing as shown in the following diagram.

The modular analog synthesizers of yesteryear were incredibly ﬂexible, partly because processing devices could be connected in any order. Modulation processors are designed according to this modular concept. They can be linked and used in a wide variety of ways limited only by your imagination. Consider the following example:

Velocity

The patch illustrated above is programmed by setting the PatchCord screens as shown below.

PATCHCORD #01

Switch

Switch On when

Velocity > 0

Switch value is Scaled by

Cord Amount

Pitch

Vel+- -> Switch +100

PATCHCORD #02

Switch -> Pitch +022

This particular modulation shifts the overall pitch up a ﬁfth when the key velocity exceeds 64. Velocities below 64 play at normal pitch. Notes with velocities of 64 and above are raised a perfect ﬁfth. The Velocity “~” source scales the played velocity around zero. In other words, low velocities (below

64) will have negative values and high velocities (64 and above) will be positive. A velocity of 64 would be zero. The Switch module only outputs a “1” if the input value is greater than zero. This digital “1” value can be scaled through the attenuator on the PatchCord to raise or lower the pitch by any amount. In this case, a scaling value of +22 raises the pitch by a perfect ﬁfth. The amount of the PatchCord on the input to the switch is unimportant because ANY velocity value equal or greater than 64 will ﬂip the switch. If the input PatchCord amount were a negative value however, the action of the velocity would be reversed and velocities less than 64 would raise the pitch and velocities equal or greater than 64 would play the original pitch.

But what if you want the velocity switch point to be something other than 64? Thanks to modulation processors, it can be done. Here's how.

Connect the DC level to the input of the switch along with the velocity value. Note that more than one modulation source can be applied to the input of a processor.

DC offset adds a ﬁxed value based on the PatchCord Amount setting. If applied to the switch along with the velocity, it changes the velocity value required to trip the switch. By setting the DC amount to a negative amount, higher velocity values are required to trip the switch. Setting the DC value to a positive value would bring the velocity switch point down. The PatchCord screens for this patch are shown below.

More Examples To derive a smooth random function you could route the Pink Noise

generator through one of the Lag Processors. A smooth random wave is useful in small amounts to add a degree of natural variation to timbre when routed to ﬁlter cutoff. Normal pink noise is low pass ﬁltered audio frequency noise with a 3 dB/octave slope to give equal energy per octave. Proteus 2000 pink noise is actually more like very low frequency ﬁltered noise, but it is perfect for use as a random control source.

The Quantizer can generate interesting whole-tone scales when envelope generators or LFOs are routed to the input. The quantizer turns a smoothly changing input signal into a series of steps. By routing the output of the quantizer to Pitch and adjusting the PatchCord amounts, you can control both the number of steps and the pitch interval of each step.

The input PatchCord amount controls how many steps will be generated. With a sawtooth wave (LFO+) feeding the input and the PatchCord amount set to 100%, sixteen steps are generated. The output PatchCord amount controls the size (or interval) of the steps.

What is a Filter? Most sounds are complex waves containing many sine waves of various

amplitudes and frequencies. A ﬁlter is a device which allows us to remove certain components of a sound depending on its frequency. For

example, a low-pass ﬁlter lets the low frequencies pass and removes only the high frequencies as illustrated in the following diagram.

A notch ﬁlter is just the opposite of a band-pass ﬁlter and is used to eliminate a narrow band of frequencies.

Another control found on traditional ﬁlters is called Q or resonance. A lowpass ﬁlter with a high Q emphasizes the frequencies around the cutoff frequency. The following chart shows how different amounts of Q affect the low-pass ﬁlter response. In terms of sound, frequencies around the cutoff tend to “ring” with high Q settings. If a ﬁlter with high Q is slowly swept back and forth, various overtones are “picked out” of the sound and ampliﬁed as the resonant peak sweeps over them. Bells and gongs are real world examples of sounds which have a high Q.

Another characteristic of a ﬁlter is the number of poles it contains. Traditional synthesizer ﬁlters were usually either 2-pole or 4-pole ﬁlters. The Proteus 2000 has selectable 2, 4, and 6-pole low-pass ﬁlters. The number of poles in a ﬁlter describes the steepness of its slope. The more poles, the steeper the ﬁlter's slope and the stronger the ﬁltering action. The tone controls on your home stereo are probably one-pole or two-pole ﬁlters. Parametric equalizers are usually either two-pole or three-pole ﬁlters.

In terms of vintage synthesizers, Moog and ARP synthesizers used 4-pole ﬁlters, Oberheim and E-MU synthesizers were famous for their 2-pole ﬁlter sound.

Using a ﬁlter, we have a way to control the harmonic content of a sound. As it turns out, even a simple low-pass ﬁlter can simulate the response of many natural sounds.

For example, when a piano string is struck by its hammer, there are initially a lot of high frequencies present. If the same note is played softer, there are fewer high frequencies generated by the string. We can simulate this effect by routing keyboard velocity to control the low-pass ﬁlter. The result is expressive, natural control over the sound.

If you use an envelope generator to control the cutoff frequency of a ﬁlter, the frequency content can be varied dynamically over the course of the note. This adds animation to the sound as well as simulates the response of many natural instruments.

Dynamic Filters

Parametric Filters A more complex type of ﬁlter is called a parametric ﬁlter or Swept EQ. A

parametric ﬁlter allows control over three basic parameters of the ﬁlter. The three parameters are: Bandwidth, Frequency and Gain. The Bandwidth allows you to select the width of the range of frequencies to be boosted or cut, the Frequency deﬁnes the center frequency of the bandwidth, and the Gain parameter either boosts or cuts the frequencies within the selected band by a speciﬁed amount. Frequencies not included in the selected band are left unaltered. This is different from a band-pass ﬁlter which attenuates (reduces) frequencies outside the selected band.

The Z-Plane Filter A Z-plane ﬁlter is a ﬁlter which can change its function over time. In a

Z-plane ﬁlter, we start with two complex ﬁlter types and interpolate between them using a single parameter. See the following diagram.

Morph

B Filter

Amplitude

A Filter

Morph

Frequency

The Z-plane ﬁlter has the unique ability to change its function over time.

Filters A and B represent two different complex ﬁlters or “frames.” Changing a single parameter, the Morph, changes many complex ﬁlter parameters simultaneously. Following along the Morph axis you can see that the ﬁlter response smoothly interpolates between the two ﬁlters. This is the essence of the Z-plane ﬁlter. Through the use of interpolation, many complex parameters are condensed into one manageable entity.

Consider, as an example, the human vocal tract, which is a type of complex ﬁlter or resonator. There are dozens of different muscles controlling the shape of the vocal tract. When speaking, however, we don't think of the muscles, we just remember how it feels to form the vowels. A vowel is really a conﬁguration of many muscles, but we consider it a single object. In changing from one vowel to another, we don't need to consider the frequencies of the resonant peaks. You remember the shape of your mouth for each sound and interpolate between them.

This Z-plane ﬁlter sweep can be controlled by an envelope generator, an LFO, modulation wheels or pedals, keyboard velocity, key pressure, and so on. In fact, any of the modulation sources can control the Z-plane ﬁlter.

78 E-MU Systems

Because creating the complex ﬁltering is difﬁcult and very time consuming, we have created 50 different types of ﬁlters and installed them permanently in ROM for your use. You simply select and use the ﬁlters in a manner similar to choosing an instrument. Because there are so many types of instruments and ﬁlters to choose from, the number of possible permutations is staggering.

The Z-Plane Filter is used to shape the harmonic content of an instrument. The ﬁlter envelope is commonly used to shape the harmonic content dynamically over time but the ﬁlter frequency can be modulated by any source. The Q parameter can be modulated only at note-on time. There are 50 types of ﬁlters available. See “Proteus 2000 Filter Types” on page 108 for a complete list of the ﬁlters.

Digitally Controlled Ampliﬁer (DCA)

Together with the Volume Envelope, the DCA is used to shape the volume contour of a sound. The DCA can be controlled by any modulation source. Velocity is often used as a modulation source for the DCA so that the harder you play, the louder the sound becomes.

Pan

Adjusts the balance of sound to the left and right channels. Pan can be modulated by any modulation source.

The following MIDI

The MIDI real-time controllers may seem confusing at ﬁrst, but they are really very simple once you understand them. You already know that there are 16 MIDI channels per MIDI cable. (Proteus 2000 has two MIDI input ports and so can accept a total of 32 MIDI channels.) Each MIDI channel uses three basic types of messages; note on/off, preset changes, and continuous controller messages. Your MIDI keyboard, in addition to telling Proteus 2000 which note was played, can also send real-time control information, which simply means control occurring in real-time or “live.” (You may be using a MIDI device other than a keyboard, but for simplicity's sake we'll presume that you are using a keyboard.) Real-time control sources include such things as pitch wheels or levers, modulation wheels or levers, control pedals and aftertouch and are used to add more expression or control.

Your MIDI keyboard sends out real-time controller information on separate continuous controller numbers. There is a set of 32 continuous controller numbers for each MIDI channel. Some of the controllers, such as the modulation wheel, volume, and pan have standardized numbers. For example, volume is usually sent on continuous controller #7. Your keyboard may have other real-time controls such as a control pedal or data sliders which can also be programmed to control the Proteus 2000.

Any MIDI controller can be routed to any modulation destination. First, you have to know which controller numbers your keyboard transmits. Most modern MIDI keyboards let you select a controller number for each control on the keyboard. For example, it may let you select a number from 0-31 for the data slider. The realtime controller numbers that the keyboard transmits must match the numbers Proteus 2000 is receiving, otherwise nothing will happen when you move the controls.

Suppose you wanted to send the four data sliders on your master keyboard. Proteus can handle 12 MIDI controllers (A-L) of your choosing. “MIDI A-L” are simply names for the internal connections that link external MIDI continuous controllers to the PatchCord section of Proteus. There are two parts to the connection. First, MIDI controller numbers are assigned to the letters A-L in the Master menu. Next, the letters A-L are connected to synthesizer control parameters in the PatchCord section of the Edit menu. The PatchCord Amount scales the amount of each controller by a positive or negative value.

MIDI Channels and Real-time Controls

The factory presets have the MIDI A-L controls connected to standard synthesizer functions (marked on the front panel of Proteus 2000). By choosing any four of the eight standard functions, your four sliders will work the same on every preset. The chart below shows how this might work if your keyboard transmitted the slider settings on MIDI controllers 12-15.

Bank Select Commands



When you press the Audition button, the Bank Select MSB and LSB are displayed on the top line of the display.

When the original MIDI speciﬁcation was developed, synthesizers had only 8 to 40 preset locations. At that time being able to select up to 128 presets didn’t seem like much of a limitation. So it was that the original MIDI speciﬁcation provided for the selection of up to 128 presets.

Musicians screamed for MORE and so the MIDI speciﬁcation was later amended to include Bank Select Commands. It was decided that Bank Select Commands would use Continuous Controllers 0 and 32 to allow the selection of up to 16,384 banks of 128 presets (over two million presets).

Because Bank Selects are implemented using Continuous Controllers, the Bank Selections can be made per channel. (This is getting better and better.) For each MIDI channel, you can select any of 16,384 banks and then one of the 128 presets in the bank. Of course no synthesizer has 16,384 banks (yet), but hey, it’s nice to know it’s possible (for that really BIG project).

Continuous Controller (CC) 0 is the MSB (most signiﬁcant byte) and CC 32 is the LSB (least signiﬁcant byte). Normally you send both the MSB and LSB controllers to implement a bank change.

Proteus 2000 remembers the MSB and the LSB that were last sent (or last changed from the front panel). For example, if you have already set the Bank MSB to 04, you need only send the LSB to change banks within the Composer sound set. See the MIDI Bank Select chart below.

The selected bank remains selected until you change it (either via MIDI or by changing the bank from the front panel). Standard MIDI Program Change commands select from 128 presets within the selected bank.

Stereo Mix Outputs

Proteus 2000 has three sets of polyphonic stereo outputs (Main, Sub 1 and Sub 2). The channels used by a particular preset (or a particular MIDI channel) can be directed to appear at any one of these three stereo outputs. This feature is useful for adding signal processing (EQ, reverb, etc.) of individual sounds prior to ﬁnal mixdown. By panning a preset completely left or right, it can be routed to a single output jack.

All presets are automatically routed to the Main outputs unless plugs are inserted into the Sub 1 or Sub 2 outputs.

Why have a Send 4 routing at all if it only goes to the Main output? The answer lies in the dual function of the Sends. Sends can be used either as Effect Sends or as External Output routing busses. Send 4 is only used as an effect send, while Sends 2 and 3 can be used as effect sends or external routing busses.

By sending different amounts of presets to the effects, subtle or striking effects can be achieved using the two effect processors. This feature allows you to get the most out of two effects since you can have eight different mixes.

The Edit menu parameters deﬁne the four layers and include the instrument assigned to the layer, the ranges of the layer, tuning, envelopes, ﬁlters, and patch cords. These parameters are deﬁned for each layer on an individual basis (based on the currently selected layer). See “Common Preset Parameters” on page 119 for global preset settings.

The Instrument parameter deﬁnes which of the available instrument sounds is played by the current layer.

To select an instrument for the selected layer(s), move the cursor to the bottom line of the display and change the instrument using the Data Entry Control.

Sound Navigator

Sound Navigator also works to help select Instruments although the category names are predeﬁned. When the cursor is on the Instrument Category ﬁeld, turning the Data Entry Control selects different instrument categories. The Name Field will change to show the ﬁrst instrument in each category. Move the cursor to the instrument name to select instruments in the selected category.

Deﬁning Layer Parameters

Deﬁning Key Range The Key parameter deﬁnes the range on the keyboard used by the current

layer. The Key range is from C-2 through G8.

Middle C

C-2 C-1 C0 C1 C2 C3 C4 C5 C6 C7 C8 G8

To deﬁne the range, set the low key value and the high key value.

You can select key numbers by simply pressing the desired keyboard key when the cursor is positioned on the low or high key ﬁeld n the display.

Fade In Fade Out

KEY: LO FADE HIGH FADE

C-2 000 C2 012

Layers can be crossfaded according to key position by adjusting the Low and High Fade parameters. The ﬁrst Fade ﬁeld determines how many semitones it takes the layer to Fade In from the low key. The second Fade ﬁeld determines how many semitones it takes the layer to Fade Out to the high key. The screen shot above and the diagram below show Layer 1 being faded out over a one octave range.

Layer 4

With a High Fade value of zero (as in layer 3 of the diagram), the layer simply switches off at the high key.

To Switch Layers According to Key Position

The Key Range parameter allows you to create a “split” keyboard with up to four sounds adjacent to each other on the keyboard. This is shown in the diagram below.

Just assign the low and high key range for each of the four layers with Fade set to zero. Set the Low and High Keys so they don’t overlap other layers.

If two layers do overlap, both will play as shown in the next example.

To Stack Layers

If the ranges of two or more Layers overlap it is called stacking layers. All Layers assigned to a key sound when the key is played. This is shown in the following diagram. It’s very easy to stack layers. Simply duplicate the key ranges for any layers you want to stack.

Deﬁning Layer Parameters

Deﬁning the Velocity Crossfade Range

Velocity is a measure of how hard the key is pressed. Velocity Range lets you control the volume of the layers using velocity. Using this function you can crossfade or cross-switch between layers according to how hard you play the keyboard.

Set the velocity range of the layer by deﬁning the high and low velocity values. Values range from 0 (off) to 127 (hardest).

VEL: LO FADE HIGH FADE

The Fade ﬁelds deﬁne the velocity crossfade range for the currently selected layer. The ﬁrst Fade ﬁeld deﬁnes the Fade In range for the low velocity value. The second deﬁnes the Fade Out range for the high velocity value.

With soft playing, Layer 1 sounds. As you play harder, Layer 1 gradually fades out and Layer 2 fades in. When the keyboard is played hard, Layer 3 plays.
