[PD] maximum of Oscillators

Oops..

I misunderstood your question.

I believe the number of oscillators in PD is limited only by your CPU.

On my machine, the CPU hovers around 93% with 336 oscillators [osc~ 800].
My machine is WinXP, 1.8 ghz, 768 mg ram.

Of course, this doesn't leave a lot of CPU for other functions.

Regards,
Dave S

Yes this i know.
But i'm looking for the amount of oscil pd can produce.
