basically I'm making a large drum soundfont and I was wondering if there was a way to map them to every key in a defined key range instead of manually defining every root key value (54 in total)
I asked myself the same question and found that if you rename the samples before loading them into the Polyphone, and use a number eg 64, 65, 66, ... automatically the program assigns each sample to the MIDI note 64, 65, 66, ... (the MIDI note correspondence table can be found by searching for "midi note numbers" eg https://newt.phys.unsw.edu.au/jw/notes.html)
But this works on individual keys (not ranges, or i don't know if is possible)
