Subject[Csnd] realtime audio, midi and fltk
Hello,

I have been working in a project with realtime audio output, midi faders and a fltk-GUI. It looks like everytime I move a fader csound stops playing audio or get dropouts. Increasing the buffers -b and -B improves performance, but I was thinking if there is a better solution for realtime midi under Mac OSX? Is portmidi the best solution for OSX? I'm running mac osx 10.4 (intel)

Hi,

I had the same problem under os x until I got rid of the FLTK bit of the code and all is well now. I am just controlling the variables with an external midi controller and the performance has been surpassingly good so far.
