[PD] Variable number of objects?

Well, as I said in my case the voices are very complex. There are hundreds
of audio objects in each voice. It takes a lot of time to adjust all of the
signal flow and reallocate the memory I guess.

Control objects shouldn't be such a big problem.

I actually meant more in general, also for non-~ signals (i.e. also control
rate .pd patches). I referred to polysynth such that people would see more
easily what I meant. Are there really no such primitives? That seems like
quite a restriction...

How can that take 10 seconds?? I dont see what would cause such a huge
overhead, i'd expect an increase in computations & memory though (say from
10 voices to 11: 10% increase in cpu workload & ram dedicated to these
voices..., I fail to see what would necessitate a long initialization...)

also, how is it done even with the long delays?

To my experience there will be definitely audio dropouts with dynamic voice
creation. In the case of my rather complex patch (with currently only 8
voices) I have to wait up to ten seconds until the patch is ready again for
playback. I am using a 3.2 GHz Athlon II X2 which is not that slow. Simpler
synth voices might be faster, though.

I think it is much better to create as many voices as needed beforehand and
turn unused voices off with the [switch~] object.

Im not sure what the best way is to instantiate variable number of objects,
for example consider polysynth.pd:

Theres a fixed number of manually placed voices, suppose I want to have the
top patch to contain a counter through which one may increase or decrease
the number of voices, how would I go about that (without manually placing a
load of voices and disabling them...)?

Whats the vanilla way to do this? Whats the pd-extended way to do this? ...
