Hi Joerg! I can't help you much further. I only knew this little twist, because someone else, told me to look there. What you did looked sometimes a bit fishy to me. I mean: if (count <98) count = 1771; This seems to be a great difference in numbers. I'd really suggest something like: if (count <1771) count = 1771; or: if (count <98) count = 98; Have you checked your little hack with other instruments? What do they sound like? Still ok? If you need more help, better ask Josh Green, Peter Hanappe or someone else from the fluidsynth-team. If you are really interested in fluidsynth, I suggest the fluidsynth mailinglist. Their mainsite is at: www.fluidsynth.org. There you'll see a link to the list.
