Hello,
Can you be more specific with your request?
You can use MIDI CCs or the Gate/CV inputs to modulate and change many aspects of Misha’s sequencer. For example, you can use gates/triggers to change key/scales/pitches/etc. You can use CVs to translate/transpose etc.
If you use an additional sequencer with Misha for these functions, you can create complex and evolving sequences. I’m sure the Acid Rain would work very well alongside Misha.
