I haven't tested score rewinding since Istvan introduced many changes, but here's how it's supposed to be used
(CppSound is a C++ wrapper for the Csound API):

void CsoundVST::synchronizeScore()
{
  vstPriorSamplePosition = vstCurrentSamplePosition;
  VstTimeInfo *vstTimeInfo = getTimeInfo(0);
  vstSr = double(vstTimeInfo->sampleRate);
  vstCurrentSamplePosition = (int) vstTimeInfo->samplePos;
  vstCurrentSampleBlockStart = vstTimeInfo->samplePos / vstSr;
  if((vstCurrentSamplePosition && !vstPriorSamplePosition) || 
     (vstCurrentSamplePosition < vstPriorSamplePosition))
    {
      if(getCppSound()->getIsGo())
	{
	  getCppSound()->setScorePending(1);
	  getCppSound()->rewindScore();
	  getCppSound()->setScoreOffsetSeconds(vstCurrentSampleBlockStart);
	  csound::System::inform("Score synchronized at %f...\n", vstCurrentSampleBlockStart);
	}
    }
}

Subject: [Cs-dev] csoundRewind() ?

I'm having trouble with csoundRewind(). I expected that
it would rewind a compiled score back to the beginning
and then the next call to csoundPerformKsmps() would start
playing it.

But after I call it, csoundPerformKsmps() doesn't budge.
Everything
else around it seems to be working, because if I send an
event to csound, then csoundPerformKsmps() plays it.

Is there anything else I should do to start the score
performance?
Of course I could call csoundReset() and do csoundCompile()
again, but that's not very elegant.

Apart from that csoundapi~ is going well; I've just got to
implement the invalue/outvalue interface before a beta
release. Compiles and runs with libcsound 5 and 4.23;
next week at work I'll try it on Linux, which should offers
the
best cs5  performance.
