This has mainly performance benefits, so that we only need to call into all processors once for every audio buffer segment. It requires adjusting quite some logic in most processors and in Track, as we have to consider a larger collection of notes and samples at each step. There's some cautionary TODOs in the currently unused LibDSP tracks because they don't do things properly yet.
