Can anyone explain more why [pd~] doesn't fulfill the desire for parallel processing, and maybe provide an example of something outside of Pd that does? I don't feel like I have a great handle on the design. As Jonathan said, it seems like Pd's determinism constraint is a big hurdle to clear, though it's already relaxed a bit with netsend/receive. What are the main differences between running an instance of Pd as a [pd~] slave to another instance, and running two instances that communicate via netsend/receive and jack?

I think we all need to learn more about multi-threading if we want to run real-time, modular, digital signal processing algorithms on multi-core machines. I, for one, can not think of any general, robust way to do this. In that sense, Pd's adherence to single threading is actually a very elegant solution to the problem.

How do you think Pure Data is limited?
for me the only real and important (i can think of at the
moment) limitation is the block-based audio processing.
to me this seems quite unnatural and inconvenient when dealing with
digital audio. it kept me for a couple of years from using pd, though it
is only a 'showstopper' in rather few cases, i found out.
feedback in large/complex patches for example, since it
is not very practical (or possible at all) to re-block
everything to 1...

what i tried but couldn't (yet): build a decent piano-roll
editor (vanilla).

and i believe too, pd has to 'learn' better multithreading to run
adequately on our future machines with hundreds or even thousands of
arm-cores...
