The Pixelator effect removes random samples from the input signal which in turn reduces the signal's quality and creates a granular type effect on the source Higher Amount settings remove more samples which reduces the signal's intelligibility. Parameter 1 - The Number 2 Knob adjusts the amount of random samples being removed from the source signal. Ranges from 1 to 50. Parameter 2 - The Number 3 Knob adjusts the edge of where the sample is being removed. Ranges from 0 to 99. FX Mix - The Number 4 Knob controls the mix of wet and dry signal. Ranges from 0 (all dry) to 99 (all wet). Master Level - The Number 5 Knob controls the Vx400s Master Level.

Detune

A Detuner will make a copy of your incoming signal, take the copied signal slightly out of tune from the original, and mix the two signals together. The result is a doubling type of effect as if two vocal parts were being sung together or two instruments were playing the same part together. Parameter 1 - The Number 2 Knob adjusts the amount of pitch difference applied to the copied signal. Ranges from -24 to 24. FX Level - The Number 4 Knob controls the volume of the detuned note. Ranges from 0 to 99. Knobs 3 has no function when the Detune effect is selected. Master Level - The Number 5 Knob controls the Vx400s Master Level.

Reverb

Reverb can give the listener a sense that the material is being performed in various acoustical environments. It can provide the tight acoustics of a small room, or the ambience of huge arena. Reverb Type/Off - The Number 1 Knob selects the Type of Reverb or acoustic environment and turns the Reverb off (OF) or on (oN). The Vx400 provides your choice of eight different 15 environments including:

Vx400 Setups

Setups Introduction
The Vx400 is equipped with four inputs and four outputs that can be configured several different ways for both live and recording applications. These configurations are selected in the DRUMS/SETUP row of the editing matrix using the five editing knobs. Settings include whether the Instrument or Line inputs are routed through the Vx400s effects processing and which pair of outputs mic, line, and instrument processing are routed to. The USB 1-2 Source and USB 3-4 Source knobs are used for configuring how all inputs, mic processing, and drum machine are routed via USB to the computer for recording applications.

Instrument/Line Setups

The Instrument and Line Setups are configurations for the instrument and line inputs designed primarily for live performance applications. The Vx400 acts as a mixing device for mic, instrument, and line sources, and can eliminate the need for a mixer when the Vx400s outputs are to be plugged directly into a full-range powered speaker system. When enabled, these inputs can be routed around or through the Vx400s effects processing and then mixed directly into the Vx400s 1/4 and XLR outputs. Both Instrument and Line inputs have four settings that can be independently selected using the Instrument and Line knobs in the DRUMS/SETUP row of the effect matrix. The configurations are as follows:
InsOFF / LINOFF - Instrument and Line inputs are disabled. insDRY / LINDRY - Inputs routed directly to Vx400s outputs, bypassing all effects processing. insRVB / LINRVB - Inputs routed through delay and reverb effects of the current preset. insFX / LINEFX - Inputs routed through all effects of current preset.

The Vx400 and Recording

Recording Introduction
The Vx400s USB connection provides 4 channels of audio streaming into the computer and 2 channels of playback from the computer simultaneously. Recording has never been easier thanks to the hands-free tracking environment that the Vx400 and Pro Tracks software provide. The Vx400s footswitches and Pro Tracks software work seamlessly together to automatically arm, record, play, and delete tracks totally hands free. Multiple recording configurations can be selected to best optimize your recording needs. These configurations are accessed via the Vx400s effects matrix in the DRUMS/SETUP row. To begin recording you must first install the proper USB drivers and Pro Tracks recording software onto your Windows compatible PC. The USB drivers are found on the X-Edit Software CD that came packaged with the Vx400 and the Pro Tracks recording software CD is found in the Pro Tracks box. Please review the Pro Tracks documentation to ensure your computer system meets the necessary requirements prior to installation and refer to the DigiTech Software Installation Guide for step by step installation instructions. Once installed and configured, the Vx400 can then control Pro Tracks and its recording functions.
Connecting the Vx400 to the Computer
The Vx400 comes equipped with a USB cable that is to be connected to your computer whenever you will be recording or using the X-Edit Editor/Librarian. We recommend that you only use the USB cable that is shipped with the Vx400 since it has been tested and approved for this specific use. To connect the Vx400 to the computer, follow these steps: Before connecting the Vx400s USB jack to your computer, consult the DigiTech Software Installation Guide and follow the instructions for your computers operating system. 1. 2. 3. 4. Begin with the power disconnected from the Vx400. Plug the small end of the USB cable in to the USB jack on the back of the Vx400. Plug the large flat end of the USB cable into an available USB port on your computer. Connect power to the Vx400.

Vx400 Recording Setup

The Vx400 has several different input / output configurations called Setups offering a wide variety of recording possibilities. These are selected using the USB 1-2 Source and USB 3-4 Source knobs in the Vx400s effect matrix. For a given recording session, you may want to record a mic with effects, dry mic, instrument, line inputs, a combination of these, or even re-mic your dry vocal tracks back through the Vx400. Up to 4 channels of audio can be sent simultaneously to the computer and the knobs in the SETUP row select how and which audio signals are routed up the USB connection. Each USB Source routes a pair of signals to the computer. The following sections outline how these signals are routed:

USB 1-2 Source

STEREO - All input sources that are routed through the Vx400s effects are sent up USB 1 and 2. MONO - All input sources that are routed through the Vx400s effects are summed to mono and sent up
USB 1. Nothing is sent up USB 2 effect - The Effect signal is sent up USB 1 and 2. Stereo track gets recorded. SUM+DM - All input sources that are routed through the Vx400s effects are summed to mono and sent up USB 1. Dry mic is sent up USB 2. SUMins - All input sources that are routed through the Vx400s effects are summed to mono and sent up USB 1. Dry instrument signal is sent up USB 2.
Dmic+i - Dry Mic signal sent up USB 1. Dry Instrument signal sent up USB 2. drymic - Dry Mic signal sent up USB 1. Nothing is sent up USB 2. DRYlin - Dry Line Left signal is sent up USB 1. Dry Line Right signal is sent up USB 2. Stereo track gets
recorded. DRYins - Dry Instrument signal is sent up USB 1. Nothing is sent up USB 2. DRUMS - Vx400 drum playback is sent up USB 1. Nothing is sent up USB 2. REmic - Playback from Pro Tracks is sent from the computer back through the Vx400s effects processing, and then sent back up USB 1 and 2 to be recorded. See Re-micing a Vocal Track on page 28 for more information on how to use this setting.

USB 3-4 Source

USBOFF - USB 3 and 4 are disabled. Dmic+i - Dry Mic signal is sent up USB 3. Dry Instrument signal is sent up USB 4. drymic - Dry Mic signal is sent up USB 3. Nothing is sent up USB 4. DRYlin - Dry Line Left signal is sent up USB 3. Dry Line Right is sent up USB 4. DRYins - Dry Instrument signal is sent up USB 3. Nothing is sent up USB 4. DRUMS - Vx400 Drum playback is sent up USB 3. Nothing is sent up USB 4.
The following diagrams show how signals are routed through the Vx400s effects and out the USB port for recording purposes:

Mic Signal Routing

The microphone signal is routed from the mic input through the Vx400s effects processing and then to the pairs of outputs. The signal sent up USB can be tapped off either at the input (USB Send Path A), or after the different Effects modules (USB Send Paths C or D). Signals recorded from USB Send Path A can be played back later through the Vx400 for re-micing. See Re-Micing a Vocal Track on page 28 for more information on how this feature works.

Utilities

USB 1-2 Level /USB 3-4 Level
The USB 1-2 LEVEL and USB 3-4 LEVEL knobs are used for boosting or cutting the amount of signal sent out the USB port to the computer. These controls are to be used if the signal level of the input source (mic, line, instrument) isnt optimized into your recording software (consult the Pro Tracks Users Guide for information on proper recording levels). If the signal is too hot to Pro Tracks, use these controls to decrease the level. The USB 1-2 Level and USB 3-4 Level knobs control the level for each USB pair of outputs so for example, if summic is the selected USB 1-2 Source, increasing the level for the mic 6dB going up USB 2 will also increase the summed signal by 6dB going up USB 1. To increase or decrease the level of audio going up to the computer, follow these steps. 1. Sing/play through the Vx400 and check the level of signal reaching the recording software (consult the Pro Tracks Users Guide for information on how to view recording signal levels). 2. Use which ever USB Level knob to boost or cut the signal level going to the recording software. The boost/cut range are -6db (usb1-2 -6) to +24dB (usb1-2 24).
Using the RPxFC for Recorder Functions
The Vx400 is equipped with a footswitch jack that lets you connect an optional RPxFC for controlling the Vx400s recorder. This 3-button footswitch features functions for STOP/UNDO, RECORD, and PLAY. The RPxFC is an ideal companion for recording as it lets you leave your Vx400 footswitches setup for changing presets while the RPxFC is used specifically for controlling the Pro Tracks recording software. Use only a TRS stereo 1/4 cable when connecting the RPxFC to the Vx400. The RPxFC functions are exactly the same as the Vx400 footswitches when it is in Recording mode. Refer to section Using the Vx400s Footswitches for Recording for operating instructions.

Factory Reset

This function resets the Vx400 to its original factory settings. This procedure erase all custom user presets, and recalibrate the Expression Pedal. ATTENTION: Performing this function erases all user-programmed data. Be sure you want to erase the memory and start fresh before continuing with this procedure. The procedure for performing a Factory Reset is as follows: 1. Disconnect the power supply from the Vx400. 2. Press and hold the Select button while re-connecting the power to the Vx400. 3. When the display reads reset?, release the Select button and press the Store button. The display reads reset indicating that the Vx400 has reset the original factory settings. At this point, the Vx400 automatically advances to the Expression Pedal calibration menu. Follow steps 4 through 7 of the Expression Pedal calibration section.

Expression Pedal Calibration
The Expression Pedal needs to be recalibrated after a factory reset. This function is automatically prompted after a factory reset. In the event the pedals calibration fails, or if the pedal does not function properly, it can be re-calibrated using the Pedal Calibration function. This does not erase the User Presets. The procedure for Calibrating the Expression Pedal is as follows: 1. Disconnect the PS0913B power supply from the power jack on the Vx400. 2. Press and hold the Down Footswitch while re-connecting the power. 3. Continue to hold the Down Footswitch until the display briefly reads calib (calibration). 4. When the display reads TOE DN, rock the Expression Pedal forward to the toe down position. 5. Press any footswitch. The display reads toe up. 6. Rock the Expression Pedal back to the toe up position. 7. Press any footswitch. The display reads VSWTCH indicating you have entered the V-Switch Sensitivity menu. 8. If you do not want to adjust the V-Switch sensitivity, press any footswitch to return to Performance Mode. Note: If error displays, an error has occurred and steps 4 through 8 should be repeated.

V-Switch Sensitivity

If you want to adjust the sensitivity setting of the V-Switch, follow steps 1 through 7 of Calibrating the Expression Pedal and then follow the steps listed below: 1. When the display reads VSWTCH, rock the Expression Pedal forward (toe down) and apply extra pressure on the toe of the pedal until the display reads DONE. 2. When display alternates between DONE (with the V-Switch sensitivity value in the numeric Display) and VSWTCHOn (or VSWTCHOf depending on whether the V-Switch is on or off), you can audition the V-Switch sensitivity by applying pressure to the toe of the Expression Pedal. 3. Rotate the Number 5 Knob to change the value of the V-Switch sensitivity. You can audition the new value by applying pressure to the toe of the Expression Pedal. 4. Once the sensitivity value is selected, press any footswitch. The Vx400 returns to Performance Mode and your settings are automatically saved.

Trouble Shooting Guide

Audio playback from Pro Tracks has pops and clicks. Try the Wave Profiler under Options->Audio. This seems to fix most problems. Otherwise, try using MME drivers in the Options->Audio->Advanced, Driver Mode selection. These are the safest drivers but also have the most latency. Try increasing the latency slider in the audio settings. Hands-Free recording on Vx400 doesnt work or has stopped working. If it was working at one point but has stopped working, try exiting Pro Tracks and then restarting it (make sure to save your project). Cycle power to the Vx400 before entering Pro Tracks or X-Edit. If it has never worked at all, there is a problem with USB MIDI The most probable causes are using incorrect or incorrectly installed drivers and/or.dll or a bad USB cable. See the section on driver installation. I cant hear audio playback from Pro Tracks. If the Remic mode in the Vx400 is active try switching to a different mode like Stereo. Make sure the faders in Pro Tracks are turned up. Check that the tracks you want to playback are un-muted. Go to Options->Audio->Drivers and under output drivers, select DigiTech USB 1-2 In/Out and de-select everything else. See the section on driver installation. My Vx400 doesnt record to Pro Tracks. Go to Options->Audio->Drivers and under input drivers, select DigiTech USB 1-2 In/Out and DigiTech USB 3-4 In Only De-select everything else. Make sure the proper drivers are installed. See the section on driver installation. For an initial track, make sure Remic mode in the Vx400 is not used. I cant get Re-Micing to work. See the Re-Micing a Track section of this users guide. Pro Tracks intermittently locks up. Close any other open programs besides Pro Tracks. Check "Task Manager" to make sure there are no hidden programs running. Try reducing the number of plug-ins and soft-synths. Increase the amount of memory in your system. Get a faster hard drive. Put your audio data on a different hard drive from your OS and applications. Get a faster computer. Please refer to the system requirements section. Where did my wave files go? Wave files all get saved to the folder specified in Options->Global, Audio Data. My waves are low/too high in level. The recording signal level can be boosted or reduced using the USB1-2 and USB3-4 level controls. Pro Tracks playback is louder than my voice. You can adjust the mix of playback versus microphone by using the Playback mix knob.
