1. Introduction

Congratulations on your purchase of the Rocktron Voodu Valve Online! The Voodu Valve Online features presets created and uploaded by Rocktron users from all over the world to Rocktron's World Wide Web site. These presets can be easily updated from the "Patch Bay" at Rocktron's web page. In addition, you can also upload your own custom presets to share with other online users. For instructions on downloading and uploading Voodu Valve presets, please visit our web site at "http://www.rocktron.com" and click "Patch Bay". The Voodu Valve Online is a 24 bit DSP professional tube guitar preamp providing 12 unparalleled effect algorithms and superb sound quality never before heard from a digital tube guitar preamp. Complete programmability and full MIDI implementation are coupled with a user friendly operating format to ensure that designing unique and useful preset sounds is as simple as possible. In addition, the Voodu Valve Online also features: Advanced Speaker Simulation provides a strikingly realistic approximation of a miked speaker cabinet at line-level for direct mixer input or headphone listening. Full parametric Pre and Post EQ gives the user complete EQ control over each preset. HUSH Noise Reduction provides noise reduction while playing and complete silence when not. "Variac" Simulation, like a conventional Variac, adjusts the level at which the preamp begins to distort. This provides more gain in high-gain applications, and allows for full-bodied cleaner presets which just begin to distort when the strings are attacked harder. Internal Wah-Wah allows the player to use an expression pedal for Wah-Wah effects instead of running long audio cables out to a conventional Wah-Wah pedal. High-quality Digital Effects, including:

HIGH GAIN Function

The HIGH GAIN function is only accessible in configurations which display "H-GAIN" in the configuration title. The preamp stage in these configurations is set up to provide high gain levels for maximum sustain and distortion.
The PARAMETER SELECT control will allow you to access these High Gain parameters:

TUBE GAIN

The TUBE GAIN parameter sets the amount of drive at the input of the tube stage. The GAIN parameter determines the gain value in the distortion stage. The VARIAC ADJUST parameter adjusts the level at which the preamp stage in the Voodu Valve begins to distort. A Variac is a voltageattenuating device that plugs into an AC wall outlet and adjusts the voltage level to any device which is plugged into it. For years, many guitarists have plugged their amplifier heads into a Variac and reduced the voltage coming into the amplifier from the AC wall outlet. This allows the amplifier tubes to reach saturation at a lower input level and increases the gain produced. The VARIAC ADJUST parameter operates in a similar manner as a conventional Variac - where lowering the parameter value lowers the level at which saturation will take place. The post BASS LEVEL parameter adjusts the amount of low frequency information at the output of each preset. This parameter is also accessible from the "Post EQ (Expert)" function. (In the Post EQ function, the center frequency and bandwidth of this EQ section are also adjustable.) The post MID LEVEL parameter adjusts the amount of mid frequency information at the output of each preset. This parameter is also accessible from the "Post EQ (Expert)" function. (In the Post EQ function, the center frequency and bandwidth of this EQ section are also adjustable.) The post TREBLE LEVEL parameter adjusts the amount of high frequency information at the output of each preset. This parameter is also accessible from the "Post EQ (Expert)" function. (In the Post EQ function, the center frequency and bandwidth of this EQ section are also adjustable.) The post PRESENCE LEVEL parameter also adjusts the amount of high frequency information at the output of each preset. This parameter is also accessible from the "Post EQ (Expert)" function. (In the Post EQ function, the center frequency and bandwidth of this EQ section are also adjustable.)

LOW GAIN Function
The LOW GAIN function is only accessible in configurations which display "L-GAIN" in the configuration title. The preamp stage in these configurations provides four distortion types, and can also be used for clean tones.

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

NOTE: There are 5 steps of the parameter adjust control between each of the intervals shown above (each step equals 20 cents).This allows for smooth pitch change when an expression controller (such as a volume pedal used with a Rocktron All Access or MIDI Mate foot controller) is assigned to the PITCH parameter to change the pitch by remote means.

CHORUS Function

The CHORUS function is available only in configurations displaying CRS in the configuration title. The Chorus effect in the Voodu Valvedddd is produced by using two delayed signals (Voice 1 and Voice 2), detuning these delayed signals (slightly changing their pitch), then modulating the detune effect 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 PARAMETER SELECT control will allow you to access these CHORUS parameters:

CHORUS I/O

The CHORUS I/O parameter determines whether the Chorus is active or bypassed for the current preset. The LEVEL 1 parameter determines the volume of Voice 1 in relation to Voice 2. The DIR/EFF MIX parameter in the Mixer function also determines the Chorus level. The PAN 1 parameter allows you to pan Voice 1 to the left or right channel. The 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 will produce a more extreme detuning of Voice 1. The RATE 1 parameter determines the sweep speed (or the speed at which Voice 1 is modulated). Lower parameter settings will result in slower speeds, while higher settings will result in faster speeds. The DELAY 1 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 LEVEL 2 parameter determines the volume of Voice 2 in relation to Voice 1.

SOURCE 2

The SOURCE 2 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 (DIR). 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 OUTPUT LEVEL 1 parameter determines the volume of Delay 1 in relation to Delay 2. The PAN 1 parameter allows you to pan the Delay 1 signal to the left or right channel. The DELAY TIME 1 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 ADJUST control, MIDI controller changes or via the Tap Delay feature (see "Operating the Voodu Valve" for detailed descriptions of each).

DLY HF DAMP

DLY TIME 1

REVERB Function
The REVERB function is available in all presets. 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 itthereby causing both the continuance of sound as well as the decaying or dying out of the sound. The PARAMETER SELECT control will allow you to access these REVERB parameters:

REV INPUT

The REVERB INPUT parameter determines whether the input to the Reverb section is ACTIVE (passing a signal) or MUTED (will not pass a signal). The MIX DIRECT/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 in relation to the direct signal and other effect signals. This parameter is also accessable from the Mixer function. 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.

Use the PRESET control on the receiving Voodu Valve to select the preset location to store the received preset. The preset currently stored at the selected location will be lost when the new preset is received, therefore caution should be used when selecting a preset location.

122 PR DUMP/LOAD

To initiate the dump, press the STORE button on the transmitting Voodu Valve. The transmitting Voodu Valve will display the preset number being dumped and "DUMPED". The receiving Voodu Valve will display the preset location being stored to and "RECEIVING." while it receives and stores the preset parameters and title.

32 DUMPED

122 RECEIVING.
After all the information for the dumped preset is stored, the receiving Voodu Valve will display "LOADED". The receiving Voodu Valve also recalls the loaded preset at this time so that it may be verified.

122 LOADED

Note: If there is an error in transmission, the unit will display "RECEIVE ERROR". Should this occur, check connections and try again. If other errors occur, check the Error Messages chart in the Appendix.
To dump a single Voodu Valve preset into a sequencer:
Connect a standard MIDI cable from the MIDI OUT of the transmitting Voodu Valve to the MIDI IN on the receiving sequencer.

!! WARNING !! Pressing the STORE button at this time will permanently erase all user presets and replace them with the original factory presets. If you have altered and stored presets which you do not want to erase, turn the FUNCTION SELECT control to exit this function.
Press the STORE button at this time to initiate the All Restore procedure and erase all current Voodu Valve presets, replacing them with the original factory presets. The Voodu Valve will display "INITIALIZING" as the Voodu Valve memory is restored.

INITIALIZING

After the All Restore process is completed, the display should read "ERRORS 0". This is the number of bytes that the Voodu Valve found that did not initialize properly. Any number of errors other than "0" means that the Voodu Valve may not have initialized properly and the process should be repeated.
Restoring the Voodu Valve controller assignments:
The controller assignments for the Voodu Valve can also be reinitialized without affecting presets and other stored information. Reinitialization of the controller assignments is necessary when setting up the Voodu Valve to operate in remote mode with a Rocktron All Access footswitch. To reinitialize only the controller assignments, enter a code number of "221" at Step 3 on the opposite page.
Selecting a Power On Preset
The Voodu Valve allows you to store a Power On preset which will always be recalled when the unit is turned on.
Turn the PRESET control to the preset number you wish to be recalled each time the unit is turned on.

34 PRESET TITLE

Recall the selected preset by pressing the RECALL button.
Press the STORE button while viewing the preset number and title to save it as the Power On preset.

Using the Voodu Valve with a Rocktron All Access in REMOTE mode
A Rocktron All Access MIDI footswitch can act as a dedicated remote control for the Voodu Valveallowing direct access to specific Voodu Valve features and parameters from the footswitch at any time.
To use an All Access footswitch as a dedicated remote, connect the MIDI OUT of the All Access to the REMOTE jack of the Voodu Valve using a 7-pin MIDI cable, as shown below.
To set up the Voodu Valve for remote operation, do the following:
Reinitialize the controller assignments as shown earlier in this section under the heading "Restoring the Voodu Valve Controller Assignments". This will match up the Voodu Valve's controller assignments to the All Access. A code of "221" must be entered to initialize only the controller information.
Turn the FUNCTION SELECT control clockwise to "REMOTE CONTROL".

REMOTE CONTROL

Turn the PARAMETER SELECT control one step clockwise to display "REMOTE".

REMOTE

Turn the PARAMETER ADJUST control to select "ON".
If the Voodu Valve titles are to be displayed on the All Access, turn the PARAMETER SELECT control to "TITLE XFER".

TITLE XFER

Turn the PARAMETER ADJUST control to "ON" to enable title transfers from the Voodu Valve to the All Access display.
To set up the All Access for remote operation, perform these steps from the All Access SETUP program: (See the All Access user's manual for detailed information on editing the All Access)

Step 8 Step 9 Step 10

Set the Operating Mode to "REMOTE". Set the Bank Size to "10". Reinitialize only the controller information for the instant access switches and pedals using a code of "231". If the preset titles from the Voodu Valve are to be displayed on the All Access automatically, set the Remote Title Number to match the Unit ID Number parameter on the Voodu Valve.
When operating in Remote mode with a Voodu Valve, switches 1-10 act as normal preset switches, while switches 1115 each perform a special function. Switch 11 switches in or out the first effect of the current configuration (not including HUSH). This can be either chorus, flange, tremolo, pitch shift, wah or phase shift. Switch 12 switches in or out the delay effect. Switch 13 switches in or out the reverb effect. Switch 14 can be pressed and held to mute the output of the Voodu Valve for as long as the switch is held down. This is especially useful when switching guitars during a live set. Switch 15 provides instant access to the Tap Delay feature of the Voodu Valve. Switch 15 can be used instead of connecting a momentary footswitch to the FOOTSWITCH jack on the rear of the Voodu Valve. For more information on the Tap Delay feature, turn to page 81.
Upon proper setup and connection of the units, the All Access will provide the functions shown above.
