[PD] maximum of Oscillators

[pix]

oh, you mean a test to see how many osc~ objects pd can run
simultaneously?

depends on your cpu. you could build an nqpoly (or clone) compatible
object, so you could easily create many osc~'s and see what the cpu usage
is like.

a note, with nqpoly, you should turn off audio computation while modifying
parameters like the number of instances, as it speeds up the garbage
collection (?) and recreation of the objects.
