Hi everyone, I'm aware that there is a score rewind function, however I 
could not find a score fast forward function, is there one? And if so 
what is it's name? Cheers,
Rory.

Thanks Istvan, I remember seeing that function before but had forgotten 
the name of it, cheers.
Rory.

I just tried that but I am not doing it right it seems. I'm just 
wondering when is the correct time to call the function? For the moment 
I create an instance of csound, I compile is with csoundCompile(), then 
I start the thread with csoundCreateThread(), it plays and I reset the 
csound. I then try csoundSetScoreOffset(), recompile and restart the 
thread. Should I be compiling first before any call is made to 
csoundSetScoreOffset()? I would try this but from the way I have 
implemented my program it's not so straightforward so perhaps you can 
give me a heads-up before I go rearranged the order in which I execute 
my API calls. Thanks again,

Rory.

I wasn't aware of the -+skip_seconds, this seems like it might be best 
and easiest way for me to do what I want. Cheers,
Rory.

Or maybe not. At the moment I have an instrument that plays a sound 
using soundin, this sound is then being written to a delay line. I would 
like to skip forward until just after the sound has been written to the 
delay line and then start the playback? Otherwise I have to listen to 
the first 30 seconds of the piece over and over again. I guess this 
means that I will need to use csoundSetScoreOffset after all. Thanks 
again for all the help,

Rory.

Now I get it. That won't work either. So does any one know a way to do 
what I want?

Rory.

Duh! Kindly disregard the question and let's pretend I didn't ask....
