1. Introduction

Congratulations on your purchase of the Rocktron MultiV alve™ guitar effects processor! The MultiV alve™ is a 24-bit DSP processor providing tube warmth to a host of high quality digital effects, as well as a number of practical features to enhance any guitar rig.

• Audio Glassics 12AX7 tube, which can be inserted into the signal path on any preset, with 2 gain settings for added tube warmth.

• Preset Spillover allows for reverb and delays from a current preset to carry over into the next preset and continue decaying when a new preset has been selected.

• Dual Channel Switching allows for programmable channel switching of amp heads, combo amps or preamps and eliminates the need for a separate channel switching device.

• Real Time Control of delay times and modulation rates through tap tempo and rate parameters. Delay times and modulation rates can be changed instantly by tapping either a momentary footswitch or the front panel T ap Delay/Rate parameter .

• High quality digital effects include chorus, delay , auto pan, tremolo, rotating speaker , pitch shift, flanger , reverb and phaser effects.

• HUSH® noise reduction operates only on incoming preamp noise, and does not affect the digital effects - which are already ultra quiet.

• Also provides compression, a four band full parameteric EQ and complete mixing capabilities.

For a thorough explanation of the MultiValve™ and all its features, please read this manual carefully and keep it for future reference. After removing the MultiV alve™ from the box, save all the packing materials in case it becomes necessary to ship the unit.

PRECAUTIONS

NOTE: IT IS VER Y IMPOR T ANT THAT YOU READ THIS SECTION TO PROVIDE YEARS OF TROUBLE FREE USE. THIS UNIT REQUIRES CAREFUL HANDLING.

POWER REQUIREMENTS

This unit accepts power from the 9VAC/3.4A adaptor supplied with the unit. This 9 volt RMS AC voltage is internally processed by a voltage doubler which generates a bipolar ±15 volts to maintain the headroom and sound quality of professional, studio quality equipment. Using an external power source such as this minimizes excessive noise and hum problems often associated with internal transformers, providing optimal performance for the user.

OPERATING TEMPERATURE

Do not expose this unit to excessive heat. This unit is designed to operate between 32° F and 104° F (0° C and 40° C). This unit may not function properly under extreme temperatures.

2. Quick Setup

SELECTING A PRESET

STEP 1 Turn the PRESET control to select the desired preset. The new preset will

be recalled automatically.

CHANGING PRESET P ARAMETERS

STEP 2 Turn the FUNCTION SELECT control to the desired effect or utility

function.

STEP 3 Turn the PARAMETER SELECT control to the parameter you wish to

alter under the selected effect or utility function.

STEP 4 Use the PARAMETER ADJUST control to select the new parameter

value.

STEP 5 The COMPARE button may be used to compare the sound of the altered

value to the stored value.

STORING CHANGED P ARAMETERS

STEP 6 After the desired parameters have been edited, press the STORE button

to store the changes into the preset.

3. Front Panel

1 POWER switch

2 PRESET control

This control scrolls through and instantly recalls the successive presets.

3 TAP DELAY/RA TE button

This button is used to select a new delay time or modulation rate based on the length of time occurring between two taps. See Section 7: "T ap Delay" for more information.

4 DISPLA Y panel

The DISPLA Y panel provides 16 characters consisting of 14 segments each.

5 COMP ARE button

The COMPARE button may be used to compare an altered parameter value to its stored value.

Note: If comparing an altered value to the stored value and the stored value

is currently being viewed, turning a knob or pressing a button that changes the parameter value displayed will cancel the previous altered value. This will also occur if a MIDI control change is received while viewing the stored value(s).

6 PARAMETER ADJUST control

This control is used to adjust the displayed parameter value. When the parameter is altered from its stored value, the LED above the STORE button will light until either (a) the new value is stored, (b) a new preset is selected or (c) the parameter is returned to its original value.

7 STORE button/led

This button is used to store parameter values into the MultiValve™ memory when altered. See "Storing Changed Preset Parameters" in Chapter 7 for more information on this procedure.

8 PARAMETER SELECT control

When adjusting parameter values, this control will scroll through the available parameters under the current function heading.

In the "Title Edit" function, this control will scroll through the character locations to be edited.

Front Panel Desccription

9 FUNCTION SELECT control

This control allows access to each function of the MultiValve™. These functions include:

Global Delay Chorus Channel Switches MIDI Channels Mixer Reverb Pitch Shift Title Edit MIDI Dump/Load Tube HUSH Tremolo Rotary Speaker Controller Assig Factory Restore Compressor Phaser Auto Pan Copy Remote Control EQ Flanger Speaker Sim Program Changes Config Select

10 BYPASS button/led

When lit, the effects are bypassed and only the input signal is passed to the MultiValve outputs.

11 INPUT LEVEL meter

These LEDs provide visual indication of the peak level of the input signal when the preset number and title are displayed. For the optimal signal-to-noise ratio, it is best to adjust the input level so that the last LED (0dB) is rarely lit. This will guard against the possibility of overdriving the unit.

These LEDs also display the final digital mixer output levels when any other functions are displayed. This will help you to guard against clipping the output of the mixer at the digital-to-analog converter.

12 INPUT LEVEL control

This control adjusts the unit’s gain to match the signal level at the input of the MultiValve™. Use the INPUT LEVEL meter to determine the setting of this control.

13 OUTPUT LEVEL control and CLIP LED

This control is used to adjust the overall output level of the unit.

The CLIP L.E.D. is part of the output section and, when lit, indicates that the final analog output is being overdriven due to the Effects Level, Direct Level and Output Level being set too high. If this should occur, reduce these levels until the L.E.D. does not light.

™

14 REFERENCE LEVEL switch

This switch adjusts the output range of the unit and may be set at either -10dB or +4dB. When using the MultiValve™ with professional studio equipment providing a nominal input level of +4dB, it is recommended that the +4 setting is used for best results. If the MultiValve™ is to be connected to a high sensistivity input, such as the input to a guitar amp, the -10 setting should be used.

1 INPUT jack

This ¼" mono jack provides input to the MultiValve.

2 Left and Right OUTPUT jacks

These ¼" mono jacks provide outputs from the left and right channels of the MultiValve™.

3 Tap Delay/Rate FOOTSWITCH jack

This ¼" mono jack is provided for the connection of a momentary footswitch to control the T ap Delay feature of the MultiValve™.

4 CHANNEL SWITCH jack

This ¼" stereo jack can be connected to the channel switching footswitch jack on an amplifier or preamp. This allows for programmable channel switching directly from the MultiValve™. .

5 PHANTOM POWER jack

This 2.5mm PIN jack offers the ability to power Rocktron MIDI foot controllers from a 7pin MIDI cable which connects from the Rocktron MIDI foot controller to the MIDI IN jack on the rear panel of the MultiValve™. This eliminates the need to find an AC outlet near where the footpedal would be placed during a performance, or the need to run an extension cord out to the footswitch. Instead of inserting the AC adaptor into the "POWER" jack of the footswitch as you would normally, plug it into the "PHANTOM POWER" jack on the MultiValve™. This will power the Rocktron MIDI foot controller through pins 6 and 7 of the MIDI cable connecting the two units. A 7-pin MIDI cable must be used and is available from your Rocktron dealer.

6 MIDI IN/REMOTE jack

This 7-pin DIN connector must be connected to the MIDI OUT jack of the transmitting MIDI device via a standard MIDI cable, or to the MIDI THRU jack of the preceding MIDI device (if the MultiV alve™ is within a chain of MIDI devices). Pins 6 and 7 of this connector carry phantom power to power a Rocktron MIDI foot controller when a 7-pin MIDI cable is used.

This connector is also provided for the connection of a Rocktron All Access™ MIDI footswitch, which can be configured as a dedicated remote footswitch for the MultiValve™. This feature allows the user to access MultiValve™ functions and parameters via the remote footswitch.

7 MIDI THRU/OUT jack

This standard 5-pin DIN connector can be connected to the MIDI IN jack of another device via a standard MIDI cable. There are limitations to the number of devices that can be chained (or series connected) in this fashion.

Note: Inherently in MIDI there is a limit to the number of devices which can be

chained together (connected in series). With more than 3 devices, a slight distortion of the MIDI signal can occur (due to signal degradation) which can cause an error in MIDI signal transmission. Should this problem arise, a MIDI Thru box can be used which connects directly to the MIDI device which transmits MIDI information and has multiple connectors for the multiple devices receiving MIDI. MIDI cables should not exceed 50 feet (15 meters) in length.

Functions and Parameter Descriptions

MultiValve Functions and Parameter Descriptions

Each MultiV alve preset is divided into individual blocks called

functions

(such as "Mixer",

"Reverb", etc.). Within each function is a set of controls which allow you to manipulate various aspects of that function. These controls are called

parameters

. The setting of each

of the parameters determines the overall sound of each MultiV alve preset.

The MultiV alve user interface is set up to allow you to first access each function (via the FUNCTION SELECT control), then the list of available parameters for the selected function (via the PARAMETER SELECT control) and, finally , the adjustable value for each parameter (via the P ARAMETER ADJUST control).

Step 3:

Turn to alter the value of the

selected parameter.

Step 2:

the selected function.

Step 1:

Turn to select a function.

The remainder of this section will discuss each of the effect-based functions and the associated adjustable parameters that they provide. Functions not discussed in this section are utility-based, and are described in Section 7,

"Operating the MultiValve".

GLOBAL

Function

Functions and Parameter Descriptions

The first function displayed when turning the FUNCTION SELECT control is the Global function. The parameters provided in this function affect all presets (i.e. the settings stored for these parameters are the same for all presets).

The P ARAMETER SELECT control will allow you to access each of the following

Global parameters:

OUTPUT

HUSH OFFSET

MUTE

DIRECT

The OUTPUT parameter determines whether the output of the MultiV alve is a stereo (left and right) signal or two mono signals.

The HUSH OFFSET parameter allows you to globally (all presets) adjust the HUSH® Expander Threshold. This means that if this parameter is altered from 0dB to +3dB, the Expander Threshold will be 3dB higher for all presets. This feature can be useful when switching from a quiet guitar with passive electronics to a noisy guitar with active electronics - as the active guitar would require a higher Threshold level in all presets.

The MUTE parameter allows you to mute the output of the MultiV alve. This feature is especially useful when changing guitars during a live set. When the MultiValve is muted, front panel controls are disabled. However, a MIDI program change will disable the mute (mute = out) and execute the program change.

The MUTE parameter can be assigned to a MIDI controller number for use with a MIDI device (such as a Rocktron All Access or Rocktron MIDI Mate).

The DIRECT parameter determines whether the direct signal is switched in or out of the signal path. When using the MultiValve in applications where the unit is connected in parallel, it is recommended that the direct signal is switched out - thereby providing 100% wet (effect) output.

This digital mixer allows you to control the signal levels pertaining to each preset’s

Mixer parameters:

LEFT DIR

RIGHT DIR

EFFECT LEVEL

DIRECT

PHS DIR/EFF CHR DIR/EFF FLN DIR/EFF REV DIR/EFF

VOLUME

The LEFT DIRECT parameter determines the level of the direct signal of the current preset at the left output.

The RIGHT DIRECT parameter determines the level of the direct signal of the current preset at the right output.

The EFFECT LEVEL parameter determines the volume of the overall effect signal (Chorus, Flange, Pitch Shift, etc.) level.

The DIRECT parameter determines whether the direct signal is preHUSH or post-HUSH. When set to pre-HUSH, the direct signal is not passed through the HUSH circuitry, or any other digital circuitry (i.e., the direct signal remains analog from input to output. When set to postHUSH, the direct signal is passed through the digital HUSH circuitry.

These DIR/EFF parameters determine the amount of direct signal input to each individual effect relative to the amount of effect signal. A setting of "0" is 100% direct signal, while a setting of "100" is 100% effect signal.

The VOLUME parameter determines the overall signal level of the current preset.

TUBE

MODE

Functions and Parameter Descriptions

The Tube Mode function is accessible in all presets—regardless of the current configuration recalled.

The Tube Mode function allows the input signal path to be routed through a high quality 12AX7 preamp tube to add a warm, vintage sound to the MultiValve ef fects used.

Function

The P ARAMETER SELECT control will allow you to access each of the following

Tube Mode parameter:

TUBE MODE When set to BYPASS, the input signal completely bypasses the tube

circuitry.

When set to LOW, the input signal is routed through the tube at a low gain setting, resulting in subtle clipping.

When set to HIGH, the input signal is routed through the tube at a higher gain setting, resulting in larger amounts of clipping and distortion.

Functions and Parameter Descriptions

HUSH

Function

currently recalled. system contained in the MultiV alve is a fully digital implementation of HUSH achieved

through Digital Signal Processing (DSP), and is modeled after the latest HUSH design. control. The analog version of the HUSH utilizes a voltage-controlled amplifier (VCA)

circuit which can control the gain between the input and the output from unity to 30, 40 or even 50dB of gain reduction. When the input signal is above the user preset threshold point, the VCA circuit remains at unity gain. (This means that the amplitude of the output signal will be equal to that of the input signal.) As the input signal level drops below the user preset threshold point, downward expansion begins. At this point the expander acts like an electronic volume control and gradually begins to decrease the output signal level relative to the input signal level. As the input signal drops further below the threshold point, downward expansion increases. A drop in the input level by 20dB would cause the output level to drop approximately 40dB (i.e., 20dB of gain reduction). In the absence of any input signal, the expander will reduce the gain so that the noise floor becomes inaudible.

The HUSH I/O parameter determines whether the HUSH circuit is active or bypassed for the current preset.

The EXPANDER THRESHOLD parameter determines the level at which downward expansion begins. For example, if the EXPANDER THRESHOLD was set at -20dB and the input signal dropped below

-20dB, downward expansion would begin.

COMPRESSOR

Functions and Parameter Descriptions

Compression is often used to maintain an even level when using clean tones, and is also used to increase sustain when using high gain distortion.

Function

The P ARAMETER SELECT control will allow you to access each of the following

Compressor parameters:

COMPRESR I/O

COMP THRESH

COMP ATTACK

COMP RELEASE

The COMPRESSOR I/O parameter determines whether the compression circuit is active or bypassed for the current preset.

The COMPRESSOR THRESHOLD parameter determines the input level (in dB) at which compression will begin. Lower settings of this parameter will result in more compression.

The COMPRESSOR ATTACK parameter determines the speed (in milliseconds) at which the compressor will reach its maximum compression level after the input signal has exceeded the threshold level (set by the COMPRESSOR THRESHOLD parameter).

The COMPRESSOR RELEASE parameter determines the speed at which compression will cease after the input signal has dropped below the threshold level.

MID LVL

MID FREQ

MID BW

The EQ I/O parameter determines whether the EQ circuit is active or bypassed for the current preset.

The BASS LEVEL parameter allows you to cut or boost the low frequencies by up to 15dB.

The BASS FREQUENCY parameter allows you to select a center frequency between 63Hz and 500Hz to be cut or boosted by the BASS LEVEL parameter.

The BASS BANDWIDTH parameter determines (in octaves) the width of the selected bass band.

The MID LEVEL parameter allows you to cut or boost the mid band frequencies by up to 15dB.

The MID FREQUENCY parameter determines a mid band center frequency between 250Hz and 2KHz to be cut or boosted via the MID LEVEL parameter.

The MID BANDWIDTH parameter determines (in octaves) the width of the selected mid band.

TREBLE LVL

The TREBLE FREQUENCY parameter determines a high band center frequency between 1KHz and 8KHz to be cut or boosted via the TREBLE LEVEL parameter.

The TREBLE BANDWIDTH parameter determines (in octaves) the width of the selected high band.

The PRESENCE LEVEL parameter allows you to cut or boost an additional high band frequency by up to 15dB.

The PRESENCE FREQUENCY parameter allows you to select a high band center frequency between 2KHz and 8KHz to be cut or boosted via thePRESENCE LEVEL parameter.

The PRESENCE BANDWIDTH parameter determines (in octaves) the width of the selected high band.

DELAY

Function

Functions and Parameter Descriptions

Delay provides a reproduction of the input signal, occurring at a prescribed time (usually expressed in milliseconds) following the input signal. The MultiV alve provides two discrete delays (Delay 1 and Delay 2), each of which has its own set of parameters to determine its particular characteristics.

The P ARAMETER SELECT control will allow you to access each of the following

Delay parameters:

DELAY I/O

MUTE TYPE

TIME1

The DELA Y I/O parameter determines whether the delay circuit is active or bypassed for the current preset.

The MUTE TYPE parameter allows for muting the delay at its input (PRE), its output (POST) or BOTH.

Muting the input (PRE) of the delay will not allow any signal to enter the delay section until the delay is switched in. When using a moderate amount of regeneration, switching out the delay with the input muted will allow you to generate a non-delayed signal which will play over the decaying regenerated signal which continues on after the delay is switched out.

Muting the output (POST) of the delay will result in the delayed signal being immediately turned off when the delay is switched out. This means that delays and regeneration will not continue when the delay is switched out. If the output were not muted, signals that were input before the delay was switched out would be allowed to regenerate, even after switching out the delay.

It is also possible to mute both the input and the output (BOTH) so that no signal enters or exits the Delay section until it is switched in.

The TIME1 parameter determines the multiplier by which a new delay time will be selected for Delay Time 1 when the Tap Delay feature of the MultiValve is used. (See Section 7: "Tap Delay" for more informa-

tion on the Tap Delay feature.)

TIME2

DELAY LVL

D-MIX S1/S2

The TIME2 parameter determines the multiplier by which a new delay time will be selected for Delay Time 2 when the Tap Delay feature of the MultiValve is used. (See Section 7: "Tap Delay" for more informa-

tion on the Tap Delay feature.)

The DELAY LEVEL parameter determines the overall level of the delayed signal at the output of the MultiValve.

The D-MIX S1/S2 parameter defines the ratio of Source 1 signal to Source 2 signal to be input to the Delay section. Source 1 is the Voice 1 output from the previous effect in the signal chain (chorus, flanger, pitch shifter, etc.), while Source 2 may be the Voice 2 output from the previous effect in the signal chain or the direct signal (selectable via the SOURCE 2 parameter). (Refer to the block diagrams shown on pages

12 and 13 for a visual representation of the input to the Delay section.)

Functions and Parameter Descriptions

Note!

When delays from the current preset are spilled over into the next preset recalled (i.e. SPILLOVER "ON"), the delay parameters for the new preset will be changed to match those of the previous preset (except for the DELAY I/O and SPILLOVER parameters) - even if the Delay effect is switched "OUT" in the previous preset.

The EFFECT LEVEL parameter in the next preset recalled does not change, therefore delays spilled into it may be of higher or lower volume - depending on the EFFECT LEVEL setting in each preset.

SOURCE 2

DLY HF DAMP

DELAY OUT 1

DLY PAN1

DLY TIME1

FINE 1

DLY RGN 1

DELAY OUT 2

DLY PAN2

DLY TIME2

This parameter is used to select whether the Source 2 input will be the VOICE 2 output from the previous effect in the signal chain or the direct signal. In configurations where there is no effect immediately preceding the delay, both Source 1 and Source 2 will be the direct signal.

The DELAY HIGH FREQUENCY DAMPING parameter controls the amount of high frequency content in the delayed and regenerated signals. Higher amounts of damping will result in less high frequency information in the delayed signal.

The DELAY OUT 1 parameter determines the volume of Delay 1.

The DLY PAN1 parameter allows you to pan the Delay 1 signal to the left or right channel.

The DELAY TIME1 parameter determines the length of time (in milliseconds) after the input signal that the Delay 1 signal will begin. The DELAY TIME can be adjusted via the PARAMETER ADJUST control, MIDI controller changes or via the Tap Delay feature.

The FINE 1 parameter allows for adjustment of Delay 1 in 1 millisecond increments.

The DLY RGN 1 parameter determines how many times the Delay 1 signal is fed back into the input and repeated.

The DELAY OUT 2 parameter determines the volume of Delay 2.

The DLY PAN2 parameter allows you to pan the Delay 2 signal to the left or right channel.

The DELAY TIME2 parameter determines the length of time (in milliseconds) after the input signal that the Delay 2 signal will begin. The DELAY TIME can be adjusted via the PARAMETER ADJUST control, MIDI controller changes or via the Tap Delay feature.

Also, recalling the same preset twice via MIDI will cancel the Spillover effect and reset the new preset to its stored parameter values (only when the SPILLOVER parameter in the recalled parameter is set "OFF").

FINE 2

DLY RGN 2

D>SPILLOVER

The FINE 2 parameter allows for adjustment of Delay 2 in 1 millisecond increments.

The DLY RGN 2 parameter determines how many times the Delay 2 signal is fed back into the input and repeated.

The SPILLOVER parameter determines whether delays from the current preset will "spill over" into the next preset when it is recalled.

REVERB

Function

Functions and Parameter Descriptions

Reverb is a multitude of echos spaced so close together that, to the human ear, seem as a single continuous sound. These echos gradually decrease in intensity until they are ultimately absorbed by the boundaries and obstacles within a room. As the sound waves from the sound source strike the boundaries of a room, a portion of the energy is reflected away from the obstacle while another portion is absorbed into it thereby causing both the continuance of sound as well as the decaying or “dying out” of the sound.

Note!

When reverb from the current preset is spilled over into the next preset recalled (SPILLOVER "ON"), the reverb parameters for the new preset will be changed to match those of the previous preset (except for the REV INPUT and SPILLOVER parameters) - even if the Reverb effect itself is switched "OUT" in the previous preset.

The EFFECT LEVEL parameter in the next preset recalled does not change, therefore reverb spilled into it may be of higher or lower volume depending on the EFFECT LEVEL setting in each preset.

The P ARAMETER SELECT control will allow you to access each of the following

Reverb parameters:

REV INPUT

R-MIX EFF/DLY

REVERB LVL

REV DECAY

REV HF DAMP

R>SPILLOVER

The REV INPUT parameter determines whether the reverb circuit is active or bypassed for the current preset.

The R-MIX EFFECT/DELAY parameter is used to define the ratio of direct signal to delayed signal to be input to the reverb section.

The REVERB LEVEL parameter allows you to control the level of the reverb signal at the output of the MultiValve relative to the direct signal and other effect signals.

The REVERB DECAY parameter determines the length of time that the reverb signal will sound before it has completely died out.

The REVERB HIGH FREQUENCY DAMPING parameter is used to control the decay rate of high frequency information in the reverb signal. Higher parameter settings will result in a faster decay of high frequency information.

The R>SPILLOVER parameter determines whether reverbs generated in the current preset will continue decaying when the next preset is recalled.When switched off, reverbs will be abrubtly cut off when the next preset is recalled.

TREMOLO

The P ARAMETER SELECT control will allow you to access each of the following

Function

The Tremolo effect continuously varies the volume of the signal.

Tremolo parameters:

TREMOLO I/O

LOCATION

TREM DPTH

TREM RATE

SHAPE

TIME

The TREMOLO I/O parameter determines whether the tremolo circuit is active or bypassed for the current preset.

The LOCATION parameter determines whether the Tremolo is located Pre-Reverb or Post-Reverb. Most vintage amplifiers used the tremolo in a Post-Reverb configuration.

The TREMOLO DEPTH parameter determines the amount of modulation for the Tremolo signal. Lower DEPTH settings produce more subtle tremolo effects, while higher settings will result in a more extreme tremolo effect.

The TREMOLO RATE parameter determines the speed at which the tremolo signal modulates (or increases and decreases in volume).

The SHAPE parameter determines the waveshape of the tremolo signal. Selecting a different waveshape produces a different tremolo effect.

The TIME parameter determines the multiplier by which a new modulation rate will be selected for the RATE parameter when the Tap Delay feature of the MultiValve is used. (See Section 7: "T ap Delay" for

more information on the Tap Delay feature.)

PHASER

Functions and Parameter Descriptions

Phase shifting involves splitting the input signal into two signals, then shifting the phase of different frequencies of one signal before mixing it back with the original signal.

Function

The P ARAMETER SELECT control will allow you to access each of the following

Phaser parameters:

PHASER I/O

PSR PAN

PSR DEPTH

RATE

P>RESONANCE

PSR STAGES

The PHASER I/O parameter determines whether the phase shift circuit is active or bypassed for the current preset.

The PHASER PAN parameter allows you to pan the phase shifted signal to the left or right channel by any amount.

The PHASER DEPTH parameter determines the modulation depth of the phase shift effect. Higher parameter settings result in the sweep of the filtering effect occurring over a wider frequency range.

The RATE parameter determines the speed at which the phase shifted signal is modulated.

The PHASER RESONANCE parameter adds feedback to the Phaser so that it has a more pronounced effect.

The PHASER STAGES parameter determines how many stages of phase shift are to be active. A parameter setting of "4" produces a result similar to a vintage Phase 90, while a setting of "6" emulates other common phaser pedals.

The FLANGER DEPTH 2 parameter adjusts the amount of modulation of Voice 2. Lower DEPTH settings produce more subtle effects, while higher settings will result in a more drastic effect.

The FLANGER RATE 2 parameter determines the speed at which Voice 2 is modulated.

The TIME2 parameter determines the multiplier by which a new modulation rate will be selected for the RATE 2 parameter when the Tap Delay feature of the MultiValve is used. (See Section 7: "Tap

Delay" for more information on the Tap Delay feature.)

The FLANGER REGENERATION parameter determines how much of the the delayed output signal is fed back into the input. More regeneration produces a more pronounced "jet airplane" type of effect.

CHORUS

Function

Functions and Parameter Descriptions

The Chorus effect in the MultiV alve is produced by detuning two delayed signals (Voice 1 and V oice 2), then modulating the detune ef fect so that the amount of pitch detune is constantly varying. Using different detune amounts, modulation rates, modulation depths and pan settings for each delayed signal will produce a greater perceived spaciousness.

The P ARAMETER SELECT control will allow you to access each of the following

Chorus parameters:

CHORUS I/O

The CHORUS I/O parameter determines whether the chorus circuit is active or bypassed for the current preset.

The CHORUS OUTPUT 1 parameter determines the volume of Voice 1.

This parameter allows you to pan Voice 1 to the left or right channel.

The CHORUS DEPTH 1 parameter adjusts the amount of modulation of the Voice 1 signal. A lower depth setting will produce a more subtle detune effect, while a higher setting results in a more extreme detuning of Voice 1.

The CHORUS RATE 1 parameter determines the sweep speed (or the speed at which Voice 1 is modulated).

This parameter allows you to select the minimum delay time (in milliseconds) for Voice 1. This delayed signal (along with Voice 2) is detuned and modulated to produce the chorus effect. Using shorter delay times will result in a tighter sounding chorused signal, while longer delay times will produce a larger ambient effect.

The TIME 1 parameter determines the multiplier by which a new modulation rate will be selected for the RATE 1 parameter when the Tap Delay feature of the MultiValve is used.

The CHORUS OUTPUT 2 parameter determines the volume of Voice 2.

This parameter allows you to pan Voice 2 to the left or right channel.

CRS DPTH 2

CRS RATE 2

CRS>DLY 2

TIME2

The CHORUS DEPTH 2 parameter adjusts the amount of modulation of the Voice 2 signal. A lower depth setting will produce a more subtle detune effect, while a higher setting will produce a more extreme detuning of Voice 2.

The CHORUS RATE 2 parameter determines the sweep speed (or the speed at which Voice 2 is modulated).

This parameter allows you to select the minimum delay time (in milliseconds) for Voice 2. This delayed signal (along with Voice 1) is detuned and modulated to produce the chorus effect. Using shorter delay times will result in a tighter sounding chorused signal, while longer delay times will produce a larger ambient effect.

The TIME 2 parameter determines the multiplier by which a new modulation rate will be selected for the RATE 2 parameter when the Tap Delay feature of the MultiValve is used. (See Section 7: "Tap Delay" for more information on the

Tap Delay feature.)

PITCH

SHIFT

note based on the input signal. The harmony voice may be of any fixed interval - up to one octave above the input signal to two octaves below - and is selected in 20-cent increments. Fine adjustment can be made in one cent (1/100th semitone) increments.

Pitch Shifting is used to change the pitch of the input signal to produce a harmony

Function

The P ARAMETER SELECT control will allow you to access each of the following

Pitch Shift parameters:

PITCH SH I/O

PSHIFT OUT

PS PAN

PITCH

The PITCH SHIFT I/O parameter determines whether the pitch shift circuit is active or bypassed for the current preset.

The PITCH SHIFT OUTPUT parameter determines the volume of the pitch shifted signal. The DIR/EFF MIX parameter in the Mixer function also affects this volume.

The PITCH SHIFT PAN parameter allows you to pan the shifted signal to the left or right channel.

The PITCH parameter selects what harmony note the MultiValve will produce based on the input note. The value displayed for this parameter represents the number of cents that the signal will be shifted (adjustable in 20-cent increments). Each 100 cents (or five 20-cent steps) above or below "0" represents the number of half-steps the shifted signal will be from the input signal.

This parameter is adjustable from "-2400" to "+1200", where "-2400" = two octaves below the input signal, "0" = unison and "+1200" = one octave above the input signal. Refer to the table on the following page to determine the cent value for each fixed interval.

FINE

PS-SPEED

The FINE parameter allows for adjustment in l-cent steps for fine adjustment of the harmony note.

The PITCH SHIFT SPEED parameter determines the amount of time delay used in the shifting process. SLOW results in the longest delay and the highest quality shifted signal (especially at larger amounts of pitch shift). FAST results in the least delay, but the lowest quality shifted signal. This setting should only be used for slight amounts of pitch shift.

Switching Channels on Amplifiers and Preamps via the MultiValve *

The MultiValve™ allows you to switch channels on an amplifier or preamp by connecting a RTS cord from the "CHANNEL SWITCH" jack on the rear of the MultiV alve™ to the "FOOTSWITCH" jack on the remote device(s). A single stereo-to-dual mono cord can also be used to connect from the MultiValve™ to two separate units. This allows for channel switching to be programmable (i.e. switched automatically when a MultiV alve™ preset is recalled) instead of having to use a latching footswitch each time a channel needs to be switched. This function can also be performed through programming a continuous controller to the CHAN SW parameter(s). See page 41, "Controller Assignments" for more information on assigning continuous controllers.

The Tip of the "CHANNEL SWITCH" jack sends the change for Channel Switch 1, while the Ring of the "CHANNEL SWITCH" jack sends the change for Channel Switch 2. When Channel 1 is on, the Tip is connected to the Sleeve. When Channel 2 is on, the Ring is connected to the Sleeve. When Channels 1 and 2 are both off, the Tip and Ring are an open circuit with respect to the Sleeve (see diagram).

Controller Assignments

The Controller Assignment function allows for specific MultiValve™ adjustable parameters to be mapped (or assigned)* to a MIDI controller for real-time control by an expression pedal.

The Controller Assignment option also lets you store an upper and lower parameter value limit which the controller cannot exceed. For example, when using an expression pedal with a Rocktron All Access™ or MIDI Mate footswitch to send continuous control changes to control the "PITCH" parameter, an upper limit of +300 can be set and a lower limit of -200 can be set - even though the actual parameter range is from +1200 to -2400. When the expression pedal is at its heel position in this example, the "PITCH" parameter will be at -200, while at its toe position it will be at +300. Up to ten controllers can be assigned for each individual preset.

Tap Delay

The MultiValve™ allows you to change the delay times and/or modulation rates for any given preset while you are

playing two different ways:

1. By tapping the TAP DELAY/RATE button on the front panel of the MultiV alve™, or

2. By tapping a momentary footswitch connected to the rear panel T AP DELAY/RATE FOOTSWITCH jack.

3. By using a Rocktron All Access™ in Remote mode with the MultiValve™ and tapping switch #15.

When any "TIME" parameter within a given preset is set to ½, ¼, TRIPLET , 8TH, 16TH or 32ND NOTE, tapping the footswitch or the front panel T AP DELA Y/RA TE button two times will change the current delay time and/or modulation rate based on the amount of time that passes between taps. The MultiV alve™ will detect the amount of time between any two taps that are less than one second apart

taps - less than one second apart - will be required to change the delay time again)

After the MultiV alve™ detects the length of time between each tap, it then multiplies or divides that time based on the type of note stored for the TIME parameter(s) of the preset. The resulting delay time can be:

• one-eighth of the time between taps (32ND)

• one-fourth of the time between taps (16TH)

• one-half of the time between taps (8TH)

• two-thirds of the time between taps (TRIPLET)

• equal to the time between taps (¼), or

• two times the amount of time between taps (½)

(i.e., if more than one second passes after the first tap, two additional

™

The maximum delay time the MultiV alve™ provides is 1000ms, therefore the T ap Delay feature will automatically default to a lower "TIME" parameter value when the time between taps requires a delay time over 1000ms. For example, if the HALF setting is stored for the TIME 1 parameter and the time between taps is 600ms, a delay time of 1200ms would be required (i.e. 600ms x 2). Because the maximum delay time is 1000ms, the MultiValve™ will default to the next lower multiplier (¼) and provide a delay time equal to the delay time detected (600ms).

"NONE" can also be selected for the TIME parameter(s) so that they will not respond to taps from the footswitch or front panel TAP DELA Y/RA TE button.

Note 1: If delay times for each preset are selected via the Tap Delay feature (instead of manu-

ally setting the parameters), the flashing front panel tap delay rate L.E.D. will accurately reflect the tapped value that was stored in each preset when it is recalled. However, the MultiValve™ must be displaying either a function heading or a parameter to store the flashing tap delay rate (i.e., not while displaying a preset title). If a preset title is displayed when the STORE button is pressed, only the Power On preset is stored (see page 63).

Note 2: If a footswitch is connected to the rear panel Tap Delay/Rate FOOTSWITCH jack when

the unit is powered up, the MultiValve™ will automatically determine the type of footswitch connected (i.e. normally open, normally closed, etc.). However, the footswitch must already be connected when the unit is turned on.

Operating the MultiV alve

Program Changes

Program Changes allow for different MIDI program numbers to be assigned to MultiV alve preset numbers. For example, MIDI program #58 can be mapped to MultiValve preset #34. Then, when program #58 is selected from a MIDI transmitting device (such as a Rocktron All Access foot controller), preset #34 will be recalled on the MultiV alve.

The Program Changes Map table is shipped from Rocktron at a one-to-one correspondance (i.e. MIDI program #1 is mapped to MultiValve preset #1, 2 to 2, 3 to 3, etc.).

MIDI Dump/Load

Any or all of the MultiV alve presets may be dumped to a sequencer or another MultiValve via system exclusive messages. The information exchanged when performing a MIDI Dump consists of parameter values, title characters and controller assignment information. When dumping a single preset into another MultiValve, the dumped preset may be loaded into any preset location on the receiving MultiValve.

To dump a single MultiValve preset into another MultiValve

Step 1

Connect a standard MIDI cable from the MIDI OUT of the transmitting MultiValve to the MIDI IN on the receiving MultiValve.

IMPORTANT: Do not allow a looping connection from the MIDI OUT/THRU of the receiving

MultiValve back to the MIDI IN of the transmitting MultiValve.

If errors occur during transmission, the unit will display "RECEIVE ERROR" for transmission errors and "XMEM ERROR" for internal hardware errors. Errors occurring in transmission does not indicate that all of the received data is corrupted. Only the transmission string where the error occurred is corrupted.

Y When receiving a Bulk Load, it is important that the data loaded to the MultiValve is not transmitted

faster than it was originally dumped from the MultiV alve. If information is sent too fast to the MultiValve, an error will occur .

When dumping information from a data storage device, such as an Alesis Data Disk, it is necessary to perform the dump in tion back to the MultiV alve at the same rate as it was received from the MultiValve. The MultiV alve can receive a data dump at about 65Hz (or about 1 byte every 15 milliseconds).
