No, I had no real purpose in building Denemo for Raspberry Pi, I was just intrigued to see if it was easy to do. And apart from changing guile-1.8 to guile-2.0 I could do it straight from the instructions on denemo.org But as I say, this showed up something strange: Portaudio couldn't find the audio output - I'm used to having to specify where the audio output should go on Unix systems, via the Preferences, but this time I couldn't hear the output via any in-built audio interface. And, as I say, even Portaudios basic test patest1.c didn't work. > > BTW I feel demeo software interface suitable for eye tracking > control. > Several months ago when I helped a course for the general public > where techno musicians make music only with a smartphone at an art > university, an ALS woman was interested in the class. > She used to study the piano, and now she can move her hands, but it > seems that most can not move. > In that class, I used the sequencer program of the module synth > tracker style of GUI called sunvox, but if the score can be read and > written, it will not fit if the program that can be controlled by eye > tracking can be built inexpensively I was wondering. > > Perhaps, if denemo can be used without problems with mouse-only or > pen-table operations, I think it may be more compatible with eye > tracking control. That's interesting - I had to look up ALS and eye tracking control, so you can tell it is not something I'm familiar with! Denemo started as very keyboard-centric and has acquired mouse features only gradually. It still doesn't do any of the new gesture stuff that touch-screens have. And its MIDI output is quite primitive - intended for checking the score is correct by listening for wrong notes/rhythms. LilyPond has somewhat better MIDI output, which is what the Playback View uses.
