        This is true too, but you'd be suprised with some of the ranges I
use... although I generally force one sample to behave as an entirely
different kind of instrument at different pitches / speeds. Unfortunately,
I played with this too much, some of my mods depended on hardware
limitations (particularly the point where sample lost tonality) -- none
of this sounded right when I got a better sound card. Heh.

        I was thinking about this. You could even put it directly into the
UI, as part of the instrument managment. Probably not ready to deal with
that yet, though.
        Getting quality sound is so much easier when generating the
sound from a couple wave generators and playing with modulation. Of
course, this still has pitfalls.
