Thanks in advance for your answers.

OK issue #1 neither Sforzando or JABB3 are GM.
#2 - JABB3 uses the mod wheel (CC1) as a volume control.
#3 - Sforzando can only load one sound at a time

The best way to achieve this is to use a DAW and put each patch on a different track.

If you want to stay in BiaB then you must put each patch on a different utility track and then use automation to raise and lower the volume of each track as needed. Note I have never done this as I do this kind of work in my DAW.

I hope this helps.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"
