2011/11/2 Iain Duncan <iainduncanlists(a)gmail.com>om>: You could implement the callbacks (and link it to STK) with Cython. (not CPython) This would require you to write a Cython-Header file for the called STK functions. Cython works very well for this, although you have to learn it, because it's neither real C nor real Python, but it's close. With some attentiveness, you could write rt- functions in Cython, because they compile to pure C / binary. No, Once per audio buffer, consisting of many (e.g. 128) samples. That's a better choice, usually, even if you do sample-by-sample processing within the function/callback. Note: Don't use python threads (as implemented in CPython), they do not work for this. You might have more luck with the more recent multiprocessing module, ( http://docs.python.org/library/multiprocessing.html ) It was introduced to circumvent some of PythonThreads limitations. -- E.R.
