I always have Auto Capture Instrument From Pattern enabled. This simplifies the cumbersome connection between the track you’re working in, and the sample you use in that track.
But. If you’re on a pattern where no notes are entered, instrument is not selected.
Please, please. Make the Auto Capture Instrument read the track in song. Not just pattern. Or add an option for this alongside the one that is already there.
