Umm, no it works as expected if you want overlapping notes. I've just
never seen that before. That isn't the behaviour SB AWE/Live gives. I
wonder where Werner Schweer got that information from? How would you
know which note to turn off when a noteoff is received, doesn't seem to
make sense to me. Ohh well, time to impliment a notesoff command then
(I'll do it :)

Right on. I wish I understood better the Filter Q description in the
sfspec. I know it is talking about the frequency response graph of the
filter, but I don't understand "DC gain" and "gain at DC". I can
understand what FilterQ does, but not the specifics of the response
graph description. I noticed you mentioned something about not
understanding the FilterQ parameter specifics in the iiwusynth source
code. Does this need to be clarified to ensure proper filter response?
Anyways. Not really important for me to understand, but probably
important for you :) Lates..
