Introduction

Aloha! And congratulations on your purchase of the E-mu Audity 2000. Audity 2000 is a new synthesizer/sound module with an array of new dynamic and rhythmic features not found in any other instrument. Audity 2000 was designed for live performance , so make sure to try out all the controller knobs on each preset. And as you’ll soon discover, Audity 2000 is a total kick to play.

Product Description

Audity 2000’s sound set consists primarily of analog, noise and modern synthesizer waveforms. These sounds are rich in harmonic texture and are perfectly matched to Audity’s powerful filters.
Audity 2000 contains 640 ROM presets, 256 user presets and gives you the power to synthesize an almost infinite number of your own sounds. Audity’s flexible yet straightforward 4-layer synthesizer voices create sounds of amazing depth and power. Layers can be switched or crossfaded using key position, velocity, real-time controllers or any modulation source. Audity 2000 also contains 50 different, 12th order resonant & modeling filters which are used to shape and modify over 200 waveforms contained in 16 megabytes (MB) of ROM. Another 16MB of ROM sounds can be added by simply plugging in a second internal SIMM card.
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, lets you connect modulation sources to 64 destinations in any imaginable way. The patch bay also contains a set of arithmetic modifiers, letting you create complex synthesis models.
Audity’s revolutionary Rhythmic Pattern Generator/Arpeggiator can play up to 16 synchronized arpeggiator patterns at once using a different sound for each! Patterns can be edited using pattern flow commands such as: delay for 2 bars, play for 4 bars, hold for 2 beats and repeat. You can program or download 100 user patterns in addition to the 200 factory patterns.
Audity 2000 Operations Manual 1

Introduction Overview
Unique to Audity is its ability to control synth parameters as well as arpeggiator tempos from its internal clock (or an external MIDI clock). Up to 8 LFOs and 12 envelopes can be perfectly synchronized at different rates!
Four front panel real-time controllers give you control over 8 user-selectable parameters as well as four arpeggiator functions. The real-time knobs can adjust multiple synthesizer functions at once allowing complex levels of control. Virtually every synth parameter in the Audity 2000 is controllable using the real-time knobs or by any internal or external control source.
Six 18-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 Audity 2000’s 24-bit stereo effects. You can choose a different effects setup for each preset from over 60 algorithms. Audity’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. The S/PDIF digital stereo output lets you connect to other digital equipment, such as digital mixers or external effects devices.

Overview

Other features include multiple solo, voice assignment and performance modes for expressive control, user-definable alternate tuning, an extremely easy to use interface and, of course, an extensive MIDI implementation.
This is the Operations Manual for setting up and playing Audity 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 Audity 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.

Outputs
Audity 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 S/PDIF output duplicates the function of the main output.

If you insert a stereo plug, 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 Audity 2000 presets without using the effects bus on the mixing board.

Selecting and Quick Editing Presets

18 E-mu Systems, Inc.
The most fundamental operation with the Audity 2000 is to select and play the factory provided presets. Audity 2000 comes with 896 presets (you can create and save your own, but that comes later). Because of the standard MIDI specification which allows only 128 presets, Audity 2000 presets are organized into seven banks containing 128 presets each. The preset is identified in the bottom line of the main screen (the screen that appears when you first power up the unit). The preset number is three digits long and first in the line. The bank containing the preset is identified by a super­script number right after the preset number followed by the preset name as shown in the following illustration.
Preset Banks 0 and 1 are copies of Banks 5 and 6 so you can make changes to the presets in the first two banks without worrying about wrecking the factory presets.

v 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 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 numer per click).
3. Play the keyboard and listen to the sounds made by your Audity 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.
Audity’s multi-channel Pattern Generator/Arpeggiator is one of the greatest features ever put in a synthesizer. Let’s start by exploring the Master Arpeggiator.
v To Arpeggiate a Single Preset:
1. Select a preset. Note that the factory presets all have prefixes which
describe the type of sound. For this investigation it might be best to choose a preset with the prefix “arp,” for arpeggiator. These presets are optimized for use with the arpeggiator.
2. Set the Arp parameter in the main screen to “M” for Master
Arpeggiator.

8. Move the cursor back to the lower left position and explore the other
parameters. The Note Value parameter changes the rate of the arpeggios. By the way, note value is a divisor based on the Master Tempo (which has its own front panel button). Try changing the tempo, but come right back.
9. Let’s check out the pattern generator. Go back to the Mode screen and
set the mode to “Pattern”.

Multi-Channel Arpeggiator

Audity 2000 is totally unique in its ability to run up to 16 arpeggiators at once! Even two or three patterns at once can create very complex sequences and dynamic landscapes of sound.
Here’s one way to access this ultra-powerful feature. There is one arpeg­giator for each MIDI channel. In order to arpeggiate on multiple channels, you’ll need a controller that can output multiple MIDI channels at once.

6. Press the Control Select button on the front panel so that the “ARP”
LED is illuminated. Adjust the front panel control knobs. Remember that the knobs are controlling the arpeggiator on the channel displayed in the main screen.
7. Try changing one of the channel’s arpeggiator setting to “M” instead of
“on.” Now press the Arpeggiator menu button on the front panel and adjust the arpeggiator parameters in real-time.

Front Panel The Audity 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 Audity 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 inforamtion begining page 25. 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.

Arpeggiator Button The Arpeggiator menu contains parameters that affect the master

arpeggiator. It also contains the User Pattern programming functions. An illuminated LED to the right of the button indicates that you are in the Arpeggiator menu.
Audity 2000 Operations Manual 23
Operations Front Panel

Left/Right Cursor Buttons

These buttons move the cursor to the next parameter on the display. (The cursor is a little flashing line underneath one of the parameters in the display.) Press either cursor button until the cursor is underneath the desired parameter. The cursor buttons have an auto-repeat feature which advances the cursor when the button is held continuously.
• The cursor can be moved bidirectionally using the Data Entry Control while either cursor select button is held down (for example, press and hold the right cursor button and turn the Data Entry Control).

Clock Button The Clock button allows you to change the Master Tempo of the unit.

Rotate the Data Entry Control to change the Master Tempo. The flashing LED to the right of the button pulses steadily to indicate that you are in the Clock menu. At all other times, the LED displays the current clock tempo by flashing on every beat.

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).

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.

Front Panel Controller Modes

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.

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

lower 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 Controller knobs provide direct control of the Audity 2000’s synthe-

sizer parameters. This mode is always active when on the Preset Select (main) screen. They can optionally be used to transmit MIDI controller messages.
The Control button 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 first two Control Rows generate MIDI A-H messages that can control the preset on the current MIDI channel (the channel showing on the Preset and main screen. The destination names (for example Filter Cutoff, Filter Attack) printed on these rows are only a template to show how the factory ROM presets are programmed to respond. You can chang the way a preset responds to MIDI A-H messages from the Edit menu (PatchCords).
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 MIDI Out” on page 61) 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 58).
Audity 2000 Operations Manual 25
Operations Front Panel Controller Modes
The third Control Row generates messages that control the Arpeggiator. Since the Arpeggiator is multi-channel, the knobs control the Arpeggiator on the current MIDI channel. If “Knobs transmit MIDI” in the Master menu is set to “transmit,” a MIDI controller message is sent when you turn the Control knob.
The knobs only generate a message when you move a knob to a new value. The current value jumps to the new value sent.

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 60).
If Quick Edit is enabled, the Arpeggiator knobs will quick edit the preset.
The Master Arpeggiator cannot be quick edited.
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 first two Control Rows’ MIDI A-H values are stored in the corresponding Initial Controller Amount parameter in the Edit menu (see “Initial Controller Amount” on page 126). 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.
v To Quick-Edit a Preset

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

Deep Edit When in the Master, Edit, or Arpeggiator menus, you can use the Controller

Knobs to edit parameters. This is called “Deep Edit” mode. Using the Controller Knobs is a faster method for entering data, but the Data Entry Control offers finer precision.
v To Enable the Deep Edit Mode:

channel arpeggiator mode is set to Off, then there is no arpeggiation on that channel, regardless of what is setup in the master Arpeggiator menu or preset. If the channel arpeggiator is On, the preset’s arpeggiator is used, regardless of whether or not it is turned on in the Edit menu. This lets you turn on arpeggiation from the main screen.
If the mode is set to “P” (for preset), the preset’s arpeggiator settings and on/off status is used. If the mode is set to “M” (for master), the master arpeggiator settings and on/off status (located in the Arpeggiator menu) are used.
v To Change the Channel Arpeggiator Status
1. Press either cursor key repeatedly until the cursor is underneath the
arpeggiator field.
2. Rotate the Data Entry Control to select arpeggiator status values “Off,

v To Set Up 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 the Audity 2000 to receive (you
can select and play up to 16 channels simultaneously). Turn all other 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
Audity 2000 to receive using the MIDI Channel/Preset selection screen (see previous instructions).
4. Audity 2000 now responds multitimbrally on each of the MIDI
channels you have specified. The volume and pan position parameters can be adjusted over MIDI (for each MIDI channel) or using the Cursor and Data Entry Control in the Preset Select screen.

Arpeggiator Menu

An arpeggiator moves a pattern of notes sequentially over a range of the keyboard. Audity 2000 has the unique ability to play a different arpeggiator on each MIDI channel!
Arpeggiator settings can be defined as part of the preset (using the Arp parameters in the Edit menu), or globally in the Arpeggiator menu. The preset and master arpeggiators have the same parameters which we define in this chapter.
The Arp field in the main screen defines which arpeggiator settings will be used. “M” uses the master Arpeggiator settings and on/off status (as defined in the Arpeggiator menu). “P” uses the preset’s arpeggiator settings and on/ off status (as defined in the Edit menu). Choosing “On” uses the preset’s arpeggiator settings regardless of whether or not it is turned on in the Edit menu and Off turns off the arpeggiator for that channel regardless of the settings and status specified in either menu.
C01 Vol127 Pan00 Arp:on

All arpeggiators share Audity 2000’s master clock and its current setting. The master clock can be Audity 2000’s internal clock or an external MIDI clock. Although the arpeggiators use the master clock setting, the tempo divisor can be unique for each arpeggiator setup.
Arpeggiator modes include up, up/down, forward assign, backward assign, forward/backward assign and random as well as play Patterns. Patterns are pre-recorded sequences of notes and rests. All key-on notes play the pattern. For example, if you play a chord, all the notes in the chord play the pattern in harmony. Audity 2000 contains 200 factory patterns and 100 user definable patterns.

Gate Time The Gate Time parameter works together with the Note Value parameter.
Just as Note Value defines the length of a note, the Gate Time sets the percentage of the Note Value time played. This can have a dramatic effect on the sound depending on how the envelope generators are programmed.
MASTER ARPEGGIATOR
Gate 100%
With a Gate Time setting of 100% the note is held on until the next note starts. The envelope generators never advance to the Release stages. With a Gate Time setting of 50%, the note is released halfway through the note cycle and the envelope generators proceed to their release stages until the next note occurs.

Extension Count 4
For example, with the Extension Interval set to 12 (an octave) and an Extension Count of 2, and with the Arpeggiator Mode set to Fwd Assign, if you played E2, then C2, then G2, the arpeggiated sequence would consist of: E2, C2, G2, then E3, C3, G3, and then E4, C4, G4.

Delay The Delay value determines how long the arpeggiator is delayed before

becoming active after the first “note-on.” During the delay period, notes are played normally (as if the arpeggiator was off). After the delay period has elapsed, the arpeggiator kicks in. Once you release all the keys on the controller, the delay starts over with the next note-on. In combination with the Duration parameter, Delay lets you change preprogrammed or played arpeggio patterns to create many more variations.

Duration This parameter defines how long the arpeggiator plays before stopping. The

Duration is specified in note values. Therefore if an arpeggio were running at a 16th Note Value and the Duration were set to a whole note, the arpeg- giator would play 16 steps before stopping. After the duration has elapsed, the arpeggiator remains inactive until the key is released.
MASTER ARPEGGIATOR
Duration 1 / 1d

Duration can be used to modify the patterns and increase the possible pattern combinations and variations. Because this parameter limits the length of arpeggiator play time, it can change the arpeggio pattern when the Duration is less than the length of the arpeggio. You can set the arpeggio to repeat continuously using the Recycle function described below .

Recycle This parameter works together with the Duration and Delay parameters.
When these are enabled without the Recycle parameter turned on, the pattern or arpeggio normally stops. The Recycle function instantly resets the pattern to the beginning after the duration value has elapsed and repeats the pattern or arpeggio.

You might want to program the effects on a global basis when in Omni or Poly modes. For example, you can choose your favorite reverb and have it apply to every preset you select. Detailed information is presented in the Effects chapter (see Effects on page 145).

Effects Mode The FX Mode page enables or bypasses the effects. When the FX Mode is set

to “bypass,” the effects are turned off on a global scale. This includes Effects programmed in the preset.

MIDI Parameters
MIDI parameters control how the Audity 2000 sends and receives MIDI data.

MIDI Mode MIDI Mode selects one of the three MIDI modes: Omni, Poly or Multi

mode.
MIDI MODE CHANGE
omni ignored
The MIDI Mode Change parameter specifies whether mode changes made through an external MIDI controller are accepted or ignored.
The MIDI modes are as follows:
Omni
Responds to note information on all MIDI channels and plays the preset currently displayed in the main screen.
Poly
Responds only to note information received on the currently selected MIDI channel (on the preset selection screen) and plays that channel’s associated preset.
Multi
Responds to data on any combination of MIDI channels and plays the specific preset associated with each of the MIDI channels. You must select multi mode for multitimbral operation.
MIDI SysEx ID This page defines the MIDI system exclusive (SysEx) device ID number . The
SysEx ID lets an external programming unit to distinguish between multiple Audity 2000 units connected to the same preset editor . In this case each unit must have a unique SysEx ID number.

MIDI Bank Audity has seven banks of 128 presets each. The MIDI specification allows
for 128 presets (without using a MIDI Bank Select command). This function lets you select which bank of 128 presets is used for incoming MIDI Program Change commands. Each MIDI channel can be set to any one of Audity 2000’s 7 preset banks. Audity 2000’s MIDI Bank parameter lets you access all 896 presets without having to send a “MIDI Bank Select” command from an external MIDI source such as your controller or sequencer.
The MIDI Bank Select command (See MIDI Specs in the Appendix) is recognized by Audity 2000 and can also be used to change banks.

Tempo is used for the arpeggiators, tempo-based envelopes, clock divisors 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, Audity 2000 redefines the center of the controller’s range as zero.

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 Audity 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

Programming Basics

This chapter explains how Audity 2000 sounds are constructed and contains important background information on how to create your own custom presets.
Your initial involvement with Audity 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 256 user locations (Banks 0 & 1) 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 any where 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.
Audity 2000 has an extensive modulation implementation using two multi­wave 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.
Audity 2000 Operations Manual 67
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.
Audity 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. Positive modulation adds to the initial amount. Negative modulation subtracts from the initial amount.

Modulation Sources

OO
Tip: Try routing Key Glide to Filter Frequency if you want the lter 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
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 control up and down in a repeating fashion. The following is a list of the modulation sources used in Audity 2000.
Keyboard Key
Which key is pressed.
Key Velocity
How fast the key is pressed.
Release Velocity
How fast the key is released.
Gate
High if the key is pressed, low when the key is released.
Key Glide
A smoothly changing control source based on the Glide Rate and the interval between the last two notes played.

Synthesizer pitch bend and modulation wheels.
Keyboard Pressure (mono aftertouch)

Pedal
A continuously variable pedal controller.
Miscellaneous Controllers A -H
Any type of MIDI continuous controller data.
Low Frequency Oscillators (2 per layer)
Generate repeating waves.
Envelope Generators (3 per layer)
Generate a programmable “contour” which changes over time when a key is pressed.
Noise & Random Generators
Generate spectrums of noise and random signals.
Footswitches
Change a parameter when the switch is pressed.
Clock Divisor
The master tempo clock can be divided and used as a modulation source.
Audity 2000 Operations Manual 69
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 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 58 for details).
When setting up modulation with the Audity 2000, you define a modulation source and a modulation destination. Then, you connect the source to the destination using “PatchCords.” Audity 2000’ s PatchCords are connected in the software. Audity 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.

Envelope Generators

Envelope Generators
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 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. Audity 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 Audity 2000’s Volume Envelope, you can simulate the different types of natural instrument volume envelopes by program­ming them appropriately.

Programming Basics Low Frequency Oscillators (LFOs)

Low Frequency Oscillators (LFOs)

A Low Frequency Oscillator or LFO is simply a wave which repeats at a slow rate. The Audity 2000 has two multi-wave LFOs for each channel. The LFO waveforms are shown in the following illustration.
Triangle
Sawtooth
SquareSine
25% Pulse33% Pulse
12% Pulse16% Pulse
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).
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.

Clock Modulation

When a PatchCord amount is a negative value, the LFO shape is inverted. For example, inverting the sawtooth wave produces a wave that increases smoothly, then abruptly resets 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.
Sawtooth
Y ou can use the Master Clock as a modulation sour ce, 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.
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.

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 with the arpeggiators 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.
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.

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:

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. 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.

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.

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 Audity 2000 has selectable 2, 4, 6, and even 12-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.

Programming Basics 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.

Right away you can see that we now have 20 different parameters to control. Ah, there's the catch. How can all these parameters be controlled effectively? 20 envelope generators? We don't think so.

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

The Z-plane lter 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
Audity 2000 Operations Manual 87
Programming Basics Dynamic Filters
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.
Because creating the complex filtering is difficult and very time consuming, we have created 50 different 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 filters to choose from, the number of possible permutations is staggering.

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 to use. Each of the 16 MIDI channels uses three basic types of messages; note on/off, preset changes, and continuous controller messages. Y our MIDI keyboard, in addition to telling the Audity 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 of the 16 MIDI channels. 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 Audity 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 Audity 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. Audity can handle 8 MIDI controllers (A-H) of your choosing. “MIDI A-H” are simply names for the internal connections that link external MIDI continuous controllers to the PatchCord section of Audity. There are two parts to the connection. First, MIDI controller numbers are assigned to the letters A-H in the Master menu. Next, the letters A-H 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.
