How about using the mpulse opcode with the frequency modulated by, say, jitter or some other randomization opcode?

In very general terms, one appraoch would be to use 2 instruments.

instrument one would consist of a kcounter, that would decrement a
 kcount on
each krate pass

something like

kcounter init (some random value in your random range (in kcounts))

kcounter = kcounter-1

if kcounter <= 0

   play inst2 (with a scoreline or event opcode from memory...)
   reset kcounter to new random value

then inst 2 is actually the thing that makes the noise on receipt of
 the "i"
score statement generated by inst 1....

steven yi has some examples using kcounter, but i don't remember where
exactly.

anyway, if you are desparate to get going (as often newbies are....)
 that
will at least give you something to think about to get started.
