Perhaps boosting priorities for time critical threads will help.
I don't know about MacOS but for Win32 something like that helps:
thread = win32api.GetCurrentThread()
win32process.SetThreadPriority(thread,
win32process.THREAD_PRIORITY_TIME_CRITICAL)
current_process = win32pr
I've been working on a Python-based music training application for a
few months, and have recently run into what I believe are some basic
limitations (or at least constraints) of Python with regards to
timing. I'll try and give a decently thorough description, and
hopefully some of you can process
