Description
It would be nice to be able to put threads into (nestable) groups which can then be stopped/started/controlled in isolation from other groups.
Currently the big Stop button stops all threads. However, it is often desirable to have some threads doing IO (perhaps mapping MIDI to OSC) which run in the background and aren't stopped when you hit Stop.
One approach would be to have a way of creating an isolated group for new threads to go in. This could be automatically used by the buffers - with each buffer automatically creating and using an implicit group. This would then allow you to start and stop all the running code in a buffer independently from other buffers.
FX chains could also be associated with groups - so that you could fade in/out, silence, solo and modify all audio created by threads in a specific group. It would make sense to map the thread groups with scsynth groups. This would potentially provide a solution for #117.
