Thanks. If you have any, or know of any, examples I'd love to look at them.
The only example I know of is zynjacku:

Implementation is C instead of C++... but same principles.

For anyone interested, it turns out there is an alpha package in rtaudio
that wraps RTAudio's callback facility in python, added this year by one of
Gary Scavone's students, Antoine Lefebvre. It's incomplete (doesn't yet
support all the rtaudio options) so it's hard to tell whether it's working
su
Thanks guys, that's very helpful. I'll no doubt have further questions once
I get to prototyping that part. Paul, if you could let me know where to
look for examples in the ardour code that would be cool too.
thanks

Yes, that's certainly feasible. RCU = Read-Copy-Update is a software
pattern for dealing with situations where you need to update a complex
data structure while it is in

I looked into this about five years ago, but didn't get too far. Wondering
if anyone on here has experience splitting apps up into:
- realtime low latency engine in C++ using per sample callback audio (
either RTAudio or Jack or PortAudio )
- user interfaces and algo composition routines in pytho
Thanks guys, it looked from what I could see on the port audio page that
only non-blocking was supported, but Gary said on the stk list that it
might be possible with the python wrappers in the rtaudio package. I
realize it's probably not going to be practical as a long term solution (

to clarify a bit more: although callback style APIs do exist (even for
*nix systems), AFAIK STK is one of the very few APIs that does
sample-by-sample processing.
