Hi
I think you'll find that p2 is the start time p3 is duration. Hope this
helps

I think I can call this off.... I think (have to check, though), it's
because I just cat the resulting audio file to /dev/audio (or
/dev/dsp, forget which one).

And I didn't set no sampling rate on the device... which may default
to 10k, or even 8k (it's an old, very old, 8-bit SB-clone (Sound
Galaxy, I think)).  So, for one second (say), CSound generates 44k
samples, which the sound card uses up at a rate of 10k samples/second
-> voila, 4.4 seconds!

An additional hint at this would have been (which alas I didn't
mention in my original post) that the pitch of the notes was as
dependent on the sample rates as their duration... the higher the
sample rate, the lower the pitch.

This means... I am very stupid.  And I gotta get a sample player, and
then I'll shut up (if this does *not* work, you're gonna hear from me
again).

Anyway,

Bye, J
