# 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 :-) -ugur-

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.
