Subject[Csnd] Score time resolution 1/4 second??
This took me a while to figure out, but the output below
clued me in.  I noticed the 'T' and 'TT' values, and I see
that they correspond to the irregularities that I was
hearing in my output.  When I stick to whole, half or quarter
beat values in the p2 score values, everything is ok.  If I
use other values for the start times (as seen below) I get
sound output the belies the 1/4 second quantization that I'm
experiencing.  I'm compiling from source, and I tried both
the old and new parser.

I just noticed that an error is counted, and I see this
'Unknown TREE node' line in the output.

Thanks for any help!

Subject[Csnd] Re: Score time resolution 1/4 second??
Ok, sorry to answer my own question (it means I
should have tried harder in the first place!!).

I was confusing the 'kr' and 'ksmps' variable.  I
had set kr = 4.  I guess instrument inits have to
start on a krate boundary, and I was only making
four per second!!

Back to music.

Thanks,

Tobiah
