Unwanted midi Data

So:

I have my voyager being controller on track 16 on channel 2

b Base set 1-4

Rom Machine on track 6 sends unwanted midi data to the voyager when tweaking certain knobs.

Whats is causing this? Do any of you fine gents know?

And how do I make it stop? Or any other possible solutions?

Yes, you can make it stop.

Change the midi channel of the voyager and midi machine to something not in the 4 channel range that is set for controlling the internal synth (1-4 in your case).

Or

Turn midi out off in the settings menu by setting the channel to “–”. Midi machines still send info, just no info is sent for the internal sequencer/synth. Clock and transpose can still be sent as they have their own settings.
