Another problem is that the minimum feedback delay is bound to the process
buffer size. No data processed -> no feedback :) Aah, analogue is so much
easier... And changing feedback delay times in realtime is surely
complicated, just imagine some really sick configurations were some
feedbacks could be depended from others...
Definitly a NO for feedback in LADSPA. Probably even for MUCOS? Anyway I
think, stuff like that should be done within one plugin.
