Look at the several Python example applications in the Csound examples directory. The most recent one is the Chua's oscillator application. On Windows, at any rate, they all permit performances to be repeatedly stopped and re-started. The C++ code in CsoundVSTShell (i.e., in CsoundVST) also does this. The CsoundVST code does this very reliably.

Hope this helps,
Mike

Thanks Mike, I will check it out.

Hi Mike. I can't see any difference between what you do in
ChuasOscillatorFrame.py and what I'm doing, that is stopping the thread 
and then calling Join(). My application is pretty complex. I will see if 
I can produce a simplified version of it and post the code. Thanks again,

Rory.

Although I can't seem to reproduce the crash I am getting I did whip up 
a minimal example that doesn't seem to work as I would expect. The 
following code(below) will start a performance, stop the performance and 
then recompile. After the recompile, Play() is called but this time 
doesn't do anything. The program just sits in silence until 4 seconds 
are up and then exits. Surely I'm doing something wrong, anyone care to 
enlighten me?

Rory.


#include "csound.hpp"
#include "csPerfThread.hpp"
#include "windows.h" //sleep function...

int main()
{
Csound* csound = new Csound;
csound->PreCompile();
csound->Compile("basic.csd");
CsoundPerformanceThread* perf = new CsoundPerformanceThread(csound);

perf->Play();
Sleep(1000);
perf->Stop();
perf->Join();
csound->PreCompile();
csound->Compile("basic.csd");
perf->Play();
Sleep(4000);

perf->Stop();
delete csound, perf;
}
