Yes, I looked at the swami code today as well, but it seems to be
quite a lot of work to do all the housekeeping and I'd really like to
keep that fluid~ external simple in general. (Also because I'm not
that good at writing a lot of C-code. ;) But maybe you could outline a
bit the way you did it or the way it can be done?

To explain what I'm after: Derek Holzer and I had this crazy idea this
weekend to abuse fluidsynth as an engine for doing granular synthesis.
Basically use a soundfont as a big collection of waveforms and play
small parts of them as grains. I'm currently just exploring, if this
is feasible at all or a very stupid idea. ;) For this application it
probably would be more apt to set gen parameters per voice. 

Ciao
