Using iPad: After populating motion samples in the Sketch section, I went to the Arrange page and created a performance track to try some of them. I muted the Main Track so I could hear only the motions I wanted to apply without the chords playing. When I went back to the Create/Sketch page nothing played there. It took a minute to figure out that if the main track is muted or any other performance track is soloed, no sound will be produced on any of the other pages. Muting the main track should only affect Section C, main track playback, not globally mute everything. I can’t think of a reason to mute anything outside the Arrange page.
