I use the SFZ version of SM_Drums in Linux.
Opening them in the free native Linux (or Windows/Mac) VST3 player, "Sfizz", lets me adjust a lot of parameters, such as pitch, pan, volume, decay, Etc. This also works on my Raspberry Pi 4.
Edit: I decided to see if I could get separate outputs from the SFZ version of SM_Drums in Sfizz, and by adding the "output=" opcode to each of the "mappings" files, I'm now getting six outputs. This is an example of the additional "output" opcode I added to the file "smdrums_sfz_ride17tip.sfz", which puts it on the 6th output of Sfizz (or whatever multi-output SFZ player you might use).
Code:
ampeg_sustain_oncc$RI17D=-100
ampeg_sustain_curvecc$RI17D=7
output=5
I now have SM Drums on separate tracks for Kick, Snare, Rack Toms, Floor Toms, HiHat, and Cymbals.
