"a stand-alone software for glitch music authoring and sound design. Gleetchlab is a modular software designed for realtime sound manipulation.
Features include convolution, granular, neural and attractors synthesis, spectral filtering, loop points manipulation, CD skip and wow & flutter simulation, vst plugins hosting, webcam controllers."
I've not had chance to download and play yet, but the features sound interesting and its free!
Might be a useful starting point for anyone interested in starting with MaxMSP to see what kinds of things can be done.
