I haven't tried this or done any debugging, but just looking at the =
code,
the following is not a good idea:

(SETQ SEQUENCE (SIM (CUE SEQUENCE) (MAKENOTE I SIG SAMPLE TS VOL
S)))=20

This looks like you are trying to append sounds together by iterating in =
a
loop. SIM and SEQ as well as some other Nyquist behaviors should not be =
used
within procedural code. Instead, so something like:
	(SEQREP (I n) (MAKENOTE ...))

Because Nyquist uses lazy (deferred) evaluation, it can be very hard to
understand when variable values are set and accessed, so it is best not =
to
use SETF with sounds. EXCEPTION: using SETF for a one-time =
initialization of
a new, local variable is OK.
