Rikki, I can't keep up - slow down!!!

The function of Soundfaction Alive is to edit the individual soundfonts (LFO, attack, etc.) as well as the soundfont wavetables (changing instruments from one wavetable to another, or importing a different standalone soundfont). I think utilizing just the instruments you commonly use and leaving the others out in a soundfont wavetable should work - I haven't tried this. Let us know how well this works. Where things may fall apart is say you utilize all the acoustic instruments (every instrument say to program change 65) and then decide to use a synth sound somewhere around 100. The soft synth may get confused with respect to the program change number (100 becomes 66, etc.).
