hi, yes, this works exactly as I intended. both examples produce the same 
result, but, thanks to the randh opcode, here's the revised, simplified, 
orchestra.

sr = 44100
kr = 4410
ksmps = 10
nchnls = 1

instr 1
   ; demonstration of variable clock frequencies
   kfreq expon 4000, p3, 40
   ; make noise
   anoise randh 20000, kfreq
   out anoise
endin

Wow, very nice. Sometimes things can get so simple :-) And another 
example that learning csound is a loooong way ;-)

Best,
Jana
