Your request is exactly the same as mine.
"It is only useful if you use the instrument as it was original labeled by BIAB" Of course request includes sorting these stems for the instruments they were originally intended. Obviously you would be able to re-voice MIDI stem after it is placed on a track. There is nothing limiting about that.

My idea, to start small and 300-400 stems that were designed for Pianos. If everything works out and there is good reception, more stems could be derived.

"However, because of the need to provide a common denominator for showcasing the styles, BIAB is limited to using General Midi patches"
That doesn't limit anything. It depends on your Default Synth and the way you have it mapped.


"Original sylemaker" is horrible. It hanged my computer a couple of times and I stopped even trying it. It is not 21st century tool...
