Treble and bass notes are rendered in one staff

[b1ueshad0w]

Most piano pieces consist of treble and bass tracks. Currently it's rendered in one staff with a lot ledger lines, making it really difficult to read.

"Piano-Roll" type works fine. Will it possible to make the "staff" type visualizer rendering the notes in treble & bass staff?

Yes, more generally, it would be great to have the option to render a separate staff for each MIDI track. That would solve this issue, provided that the bass and treble tracks are actually separate MIDI tracks.

This would probably require changes to the visualizer code, which is currently in @magenta/music, or directly to staffrender, which is used by @magenta/music to render the staff.
