Vx400 Drums and MIDI
The Vx400’s Drum machine samples are mapped so that they may be triggered by MIDI notes played from
Pro Tracks™. Each of the drum patterns programmed in the Vx400 has been programmed as a MIDI track in
the Pro Tracks project file library.
Note mapping for each of the Vx400’s drum samples is as follows:
MIDI Note Sample
36/C3 . . . . . . . . . . . . .Kick
38/D3 . . . . . . . . . . . . .Snare
42/F#3 . . . . . . . . . . . .Closed High Hat
46/Bb3 . . . . . . . . . . . .Open High Hat
Recording the Vx400 Drums
The Vx400’s drum machine can be recorded using Pro Tracks. Each of the Vx400 drum patterns have
been saved as pattern template files which can be selected from the Pro Tracks project file library for
playback control of the Vx400’s drum samples. To record the Vx400 drums using the pattern templates
provided in Pro Tracks, follow these steps:
1. From the Pro Tracks menu bar, select File>New. The New Project File window will appear.
2. Select one of the DigiTech Vx400 drum templates and click the OK button. This will open up a new
recording session.
3. On the Vx400, use the either USB 1-2 Source or USB 3-4 Source knobs to select
drums.
4. Press the RECORD footswitch. The Vx400’s display reads
record.Anew track is automatically
inserted in the current session of the Pro Tracks software and recording on these tracks begins.
5. To stop recording, press the STOP/UNDO footswitch.
You can use MIDI drum files for playing the Vx400 drum samples if you like as long as the events are
mapped to the MIDI notes shown above. The drum samples of the Vx400 only respond to MIDI messages
transmitted on MIDI channel 10, which is the default channel for General MIDI drums.
Playback Mix
The PLAYBACK MIX knob is an easy way to balance the Vx400’s processing with playback from the Pro
Tracks software using a single control. This function is only available when the Vx400 is connected to the
computer via USB and Pro Tracks is up and running. To change the Vx400/Playback mix, follow these steps:
1. Start playback of a session from Pro Tracks.
2. Turn the playback mix knob to balance the level of Vx400 vocal processing and playback level. When the
display reads
USBMIX 0 indicates that only Vx400 signals will be heard. Rotating this knob clockwise, you
will begin to hear the playback level increase.
USB VX50 indicates the Vx400/computer playback mix is a
50/50 mix of both signals. Continuing to rotate the knob clockwise will decrease Vx400 level.
Vx MIX 0
indicates that only playback from the computer will be heard.
