Arturia Keystep - sequencing multiple midi channels in same sequence?
As I understand you can use 8 notes per step.. But can you use multiple midi channels for each note on that step? So , What I want to do is make a sequence containing notes on 8 midi channels.. So I want to record a bassline on channel 1, lead on channel 2, drums on channel 10 etc… And all in the same sequence. Is this possible?
