After a further play this afternoon there is a small information button labelled "i" near the orange circle towards the middle/bottom of the UI. If you click that it overlays information about what the various areas do.

The blue keys let you enter "chord shapes" in triads, the 1st octave yellow/red keys control the pattern for the bass clef, the 2nd octave for the treble clef (unless they are linked by clicking the big upward arrow), and the green keys 1 key chords.

The mod wheel can also be used to control the volume of treble/bass instruments if the semi-circle symbol top left on each clef is enabled. The black keys with the power on/off symbol can be used to disable the bass clef.

That's all for now.
