Thanks for the recommendation, just installed and played around with it.
However, I realize now that I wasn't clear enough in my original post. As far as I can tell, this sampler is similar to Sitala in that it assigns one sample to one MIDI note. Instead, I want each MIDI note to play the same sound but at different pitches. So a C5 should play my sound at the pitch C5, a C4 should play my sound at a C4, etc. ADSR is able to do this but distorts the hell out of my sound when I stray too far from its original pitch.
