Thank you Franck and Michal for your experience and hints. I'll peek into pd. It seems to have a very active community. RTMix looks very interresting, and is the kind of glue I may need. As a beginning, I'll try to make PD and Hydrogen and RTMix work together. It may all end with a "live mode" for Hydrogen build from libhydrogen, even though I don't know C++ programming. If anyone has perl bindings for libhydrogen, I would be happy :). Regards, -- Charles
