I'm trying to use csoundPerformBuffer with host implemented audio
output (no host audio input, yet) and it works well for the first run
through of the .csd but after stopping playback and calling
csoundRewindScore, csoundPerformBuffer doesn't seem to be
acknowledging the score as rewound, always returning true (score
finished).  Resetting and recompiling works
(csoundReset/csoundCompile) but is undesirable.

Is this a bug or am I incorrect in assuming csoundPerformBuffer should
read score events from the beginning after calling csoundRewindScore?
I've always used csoundPerformKsmps before, so I'm not sure.

Cheers,
~ andy.f

Hi Steven,

Perhaps "stopping" was a poor choice of words.  Here is the sequence
of calls ...

csoundCompile(...);

while (!csoundPerformBuffer(csound))
   copy_csound_output_buffer();

csoundRewindScore(csound);

... all subsequent calls to csoundPerformBuffer return true.

Stepping into the csound source reveals the only score event being
processed is 'e'.

Cheers,
~ andy.f

Ok, thanks.  I will make a test case and submit a bug report if it is a bug.

Just as a curiosity what was the problem?

Oh yes, I thought that it was something to do with memory files. I wonder if the other API functions dealing with score transport need similar fixes.

No, it appears csoundSetScoreOffsetSeconds() should be fine as it depends on csoundRewindScore().
