What happens if you stop the playback after you do the fill, mute the filled track that caused the change and then start playback again? Is the melody of synth 2 still changed? Or does it play the expected melody?
If the melody of synth 2 then plays what you expect, what happens then when you unmute the filled track?
yes, if I stop and then start playback the other synths melody goes back to normal for a second and then reverts back to the altered one.
if I stop playback, mute the new synth and then play the other synth is normal and doesn’t get affected. if I unmute it the other synth goes weird again.
