VX20 MIDI
A MIDI signal connected to a VX20 wing can be used to remotely control the playback of the
“selected” playback that wing. A playback is selected on a wing by pressing

then any of
the flashing buttons of that playback. The cue-list name of the currently selected playback is
displayed in black text on a white background.
MIDI “Note ON” messages can be assigned to trigger the Go, Pause/Back, Release and
Jump functions of the selected playback on a VX20 wing.
MIDI “Control Change” messages can be used to pre-select a cue in the cue-list of the
selected playback that will be triggered by the next “Note on” message to be received
that is assigned to the “Jump” function.
