ah, indeed, there are differing input selects for Pickup Machines after all, so, 61 does not map to A:B 60 does, as A:B provides a combo record option, so to replicate A:B pressing behaviour I guess go with 60 and 64 to mimic C:D, either way, it’s all laid out in the back of the manual, having the ability to cherry pick the inputs is quite handy, thanks for bringing this nuance out
