When you use "Automatically detect beats/transients - on a loop, how do I make certain that the first slice starts at C?
(they all (= by this I mean that any loop that I slice seems to) seem to start at B which is really confusing)
I’m probably missing something really simple, so please point me toward it
Since it’s necessary for Renoise to handle the mapping of sliced instruments automatically, you will need to use the Generate Drumkit function instead. If you Generate Drumkit with B-3 as the base note, then the original unsliced sample will be mapped to B-3, while the first slice will start on C-4 as you want (instead of C#4 which is the default).
Not instead, but using the drumkit generator after slicing to adjust the key-assignments.
