CMKeyboard is a 128 note ALSA MIDI virtual piano keyboard spanning from
C-1 to G9 written in python3 and taking advantage of the latest Clutter
(>1.12.2) features to enable scrolling and opengl goodness. It is a stand
alone program which can also be embedded into other python3 applications
as a class library. It uses code from the very handy pyclutter-widgets
project for the rounded rectangles of the key buttons.
The code demonstrates use of Clutter.ScrollActor(), GtkClutter.Embed(),
layering of multiple clutter actors, handling of events including:
"button-press-event" & "key-press-event".
