First of all, thank you for using the tool and comments!
having instruments on thier own channels can lead to problems if theres multiple channels using the same one
Thanks for the report. You’re right: assigning multiple samples to the same MIDI channel may cause problems. Channel assignment is left to the user, so you can control routing, but please avoid assigning the same channel to multiple samples.
Notes: channels 1–8 may be used by the SPC emulator, and channel 10 is reserved for drums, so the following channels are generally available: 9, 11, 12, 13, 14, 15, 16.
Side Pocket, Aero the Acrobat 2 and Battletoads remixes here I come

Thanks, it is my pleasure to use the tool. I can’t wait to see what you make.
