Hi,

Rewriting the second example yields the following instrument which still has
the tuning problem:

          instr  2

icps      =      cpspch(p4)
iamp      =      p5
kamp      linseg iamp, 1/icps, iamp, 0, 0, p3-1/icps, 0
asig      init   0

anoise    rand   kamp

adel      delayr 1/icps
          delayw asig
asig      tone   adel+anoise,sr/2

          outs   ganull, asig
          endin

Making the following change solves the tuning problem.

adel      delayr 1/icps
asig      tone   adel+anoise,sr/2
          delayw asig

Setting sr=kr also solves the problem.

Hope this helps,
Hans Mikelson
