That's C-code, iirc. The problem with python: the interpreter has a global lock (the

The current software thought is to have both
sides have two threads: one thread
running callback to JACK, the other handling UDP/TCP, the threads communicating
by Python FIFO queues, the UDP/TCP thread being constrained by 31.5kHz wait-state
Use jack ring buffers for thread communication. They are rt safe. I have
used them with a midi to qwerty keyboard bridge. (see:
