Hi Peter,

Yes i will check debug/optimization flags and link.

It seems a bit complex to debug since the dll that use the static iiwusynth
code is loaded by MidiShare (and not by the system) and the  debugger seems
not to go into this code.

I'm not using DirectSound, i'm trying the PortAudio code.

Because i would like to reduce the number of dll, i have :
mshare.dll that use msSynthDriver.dll that contains the iiwusynth code.
