…anyway if you are working on the full mix and fully wet or near fully wet you will notice a 50ms gap when changing presets with different characters, so program changes needed to be send 50ms in advance or you will cut the first 50ms of the first Bar. Program changes sent by the Octatrack while changing Patterns are sent even earlier so the AH preset change won’t be quantised neither.
That’s why I use Max to change presets on my AH, perfect quantize, and no gaps.
