Nonetheless,
if I have 40 instances of zyn, I'd
like to (actually must) compute them concurrently. So how to do this with
one client?
By using your own internal graph mechanism that has parallel capabilities.
See, for excample,
https://github.com/flowprogramming/dspatch
This one is based on pthread_cond_wait(), which is either implemented as a spinlock or not
realtime safe (I guess the second). So how can this help?
The best way I
can see is using an array of jack clients, and hoping
they'll process() at the same time. However, this sounds very tricky...
There can be very good reasons for using JACK 1. If a user is doing that,
you won't get any parallelization at all.
Does JACK 2 allow to use multiple jack clients that call process() at the same time? Or
does it allow to enter process() with multiple threads? There seems to be no
documentation/tutorial about JACK 2.
