Announcing CMKeyboard http://djcj.org/cmkeyboard 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". -- Patrick Shirkey Boost Hardware Ltd
