Crossfader and scenes are sent on the lowest midi channel of the audio tracks not shared with a midi track channel…
Ex : if the lowest audio tracks midi channel is 1 and shared with a midi track using the same channel : CC48 is sent on channel 2.
If all audio channels are shared, or if they are Off, nothing is sent.
Same rule as AUTO setting in MIDI SYNC page. It doesn’t correspond to AUTO CHANNEL as on other Elektrons, but to the lowest audio track channel (not shared). Confusing, isn’t it ?
Also :
if several midi tracks are assigned to the same MIDI channel the track with the lowest number has priority in regard to parameter collisions.
So if the same CCs are sent on several tracks, they will be sent only on the track with lowest midi channel, unless you mute it…
(Had to test it with a midi monitor)
