Thanks Gonzalo for working on this awesome addition to the activity 
suite. I played a bit with it today and here a few feedback items:

- the initially selected instrument is not selected, when I change the 
instrument, it is selected fine. As the widget to select an instrument 
is a list depending on the selection you can not always see the selected 
instrument, maybe you want to show the currently selected instrument as 
well in the toolbar or make that clear by other means

- it is great that you can show different labels on the keyboard, the 
icon for the hardware keyboard mode is not really clear maybe you can 
reuse the icon from the Sugar control panel, I would add tooltips to the 
icons (they should hide automatically when you click the icon, recent 
fixes have anded for this in the sugar-toolkit-gtk3), finding good text 
for the tooltip involves a bit of research I guess [1], it would be 
great to have no-labels at all mode as well

- when I hold down 'w' and 'r' pressing 't' will not give any visual or 
musical feedback - 'y' or 'u' does work, same that 'z' and 'c' work but 
'x' does not when holding down 'w' and 'r' at the same time

- sound: this is a question for the OLPC audio developers, there is a 
lot of noise and clipping while playing - would be fantastic to fix this 
as well

-------------

Future-future: it would be great to show the corresponding note in the 
musical representation [2], [...] recording would be nice, play-along 
[...] but that probably let the scope of the activity explode :)
