kleines Filmröllchen 0ab19dc4cd Piano: Allow per-track controls (again)
This makes Piano exactly as usable as when I started the large refactor
some years ago, which *sounds* like I'm a terrible person but now it (1)
looks nicer and (2) has a flexible backend that can already deal with
aribtrary kinds of processors on any track.
