in reply to listen to a midi keyboard

"...the musical notation software lilypond"

I don't know very much about MIDI but i know a little bit about musical typesetting.

IMHO you should think about a commercial solution instead of using lilypond.

Or do you really want to learn Scheme?

If so, i wish you well ;-) You need to do this if you want that lilypond does what you want.

    Dear Carl, I've been working for Years with Sibelius but I changed to lilypond, because it's better, in my opinion! I don't have any problems with the syntax, although I didn't learn scheme. The only thing I'm missing is the possibility of midi input via keyboard. I just wanted to know if perl could help me with that!

      OK, i surrender, sorry.

      But did you really like something like this:

      F = #(let ((m (make-music 'ArticulationEvent 'articulation-type "flageolet"))) (set! (ly:music-property m 'tweaks) (acons 'font-size -3 (ly:music-property m 'tweaks))) m) \relative c'' { c4^\F c4_\F }

      Shit, looks like elisp ;-)

      Update: BTW, Avid killed Sibelius.

      My best regards, Karl

        Nonsense. Lilypond isn't exactly pretty, but in my experience with it (years ago), I never had to drop into Scheme to typeset ordinary music.

        But to address the OP's question, if you can get at MIDI-format data, there's MIDI to convert it into Perl data structures.

        Just because lilypond is programmable doesn't mean you must program it. (Same applies more-or-less to LaTeX.)

    Could you please explain your observed (non)relation between "commercial solution" and "Scheme"?
