Using an External MIDI Device to Control the Mixer (Compu Mix)

The VS-1824 can send and receive mixer settings and fader movements as MIDI messages. You can use an external MIDI controller to control the VS-1824’s faders. You can also use an external MIDI sequencer to record mixer settings and movements during playback as MIDI song data, and the mixer can be controlled automatically by the MIDI sequencer when the song is played back later. This is referred to as Compu Mix. Compu Mix uses Control Change messages or System Exclusive messages.

When using System Exclusive Messages

When working in Compu Mix, you should normally use Control Change messages. However, if the Control Change messages affect the settings of other MIDI devices in your setup, you can use System Exclusive messages. For more detailed information about Control Change messages and System Exclusive messages, refer to “MIDI Implementation” (Appendices p.82).

Correspondence Between MIDI Channels and Controller Numbers

MIDI channels correspond to the mixer channels as shown below. For channels paired using the Channel Link function, Control Change messages can be exchanged using the odd- numbered channel’s MIDI channel. Control Change messages transmitted via the even-numbered channel’s MIDI channel are ignored.
