What choices do I have for sound design and fx in surround? Do I really need to write PureData patches for everything? Does AlsaSynthModular support multichannel output? It doesn't have a multichannel panner, but I guess I could build one. Perhaps even connect a joystick. Are there any surround patches available, as a starting point?
A really good multichannel reverb would be cool too, but that is hardly available on win/mac, so I'm not holding my breath.
