This activity born as a proof of concept for a piano keyboard widget, with the idea of add this widget to the existing TamTam suite. This widget should be usable with touch devices, as the XO-4, and support multiple touches, then we need use Gtk3 (Gtk2 only support a simple toch emulation). The [http://wiki.sugarlabs.org/go/Features/GTK3/Porting/TamTam port of TamTam suite to Gtk3] already started, but is complex and need more work.

The piano widget trigger events for every key pressed/released, and is designed to be easily included in other activities.

The part of the code needed to play the notes, is copied from TamTam suite. The backend is using csound, but has not been improved in a lot of time.

Note the master branch in the TamTam repository is where the port to Gtk3 started, but is not finished. If you want generate a usable activity, should use the branch sugar-0.94

There are code, actually commented, to record sounds in TamTamMini activity. I don't know if the code is working or not, but is a alternative to explore.

The activity TamTamJam use sequences of notes as loops to play. Can we save a loop in MusicKeyboard? Should be good for interoperability.

Other options to explore, is check if we can save the key press/release events, or convert to a more useful format as midi.

Daniel Francis proposed: "I have been working some time ago on a staff widget to show the notes [1]. Has pending to draw notes with sharps and flats (black keys in the piano)."

Another option is show the notes aas horizontal bars as the TamTamEdit activity do, maybe is more intuitive for kids.
