# Thanks for the hints. After I changed expr~ with tabread~ the cpu consumption decreased dramatically.
# As a I understand the Vosim patch, sinusoidal harmonics model of sound is not useful for speech. It is very interesting that repeating N successive decaying sin^2 peaks sounds like a vowel.
# In my PD distro (0.39.2-extended-test7) [polypoly~], [nqpoly4]  does not exist. So I can't use them.
# The attachment includes improved version of the study patch. Main patch is granuler03.pd. You can open it and listen to the sound of cicadas in the middle of night :-)

Some hints: For granular synthesis you definitely want to avoid line~
and use vline~ instead. Alternative approaches could be made with
phasor~ and samphold~. The Vosim patch I posted recently is also a
granular technique. In Vosim, the waveform is a squared sin, the
envelope is a exponentiall falling step function for each sin^2 peak,
but you could change that of course to produce different waveforms and
envelopes, just replace the cos~ stuff with tabread4~s and scale the
phasors accordingly. (tabread4~ would be faster in your patch as a
replacmenent for expr~, too)

And yes, you need many copies of each, so something like [polypoly~]
or [nqpoly4] will help.
