Hmm, let me try to relate this question with Lilypond. My guess is that you are writing a text editor for entering Lilypond music. Whenever a note value is entered you want to hear it, so that instead of listening to the midi proofreading output afterwards you can immediately hear which note you enter. If you are a fan of the command line and mean & lean text oriented programs, you might look at the curses/ncurses library for the input. That is an old but still frequently used library which enables you to do anything with text in a console or an xterm(-like) window, in particular you can assign actions to separate keystrokes. Or undoubtely you can hack Emacs syntax file for lilypond such that note values can be assigned to sound events. If you wish to go for a more graphical solution you'll probably look at the Qt and/or GTK/glib libraries which also have libfunctions for dealing with keyboard input. The actual sound part is a bit harder. I have no programming experience with sound but I'm afraid that this is dependent on platform and desktop environment: e.g. whether the sound output is governed by a sound manager like Arts or Esound, or that you can do direct OSS or ALSA calls. Maybe there is a clever midi playing library (or a cmdline program accepting stdin) which solves & hides all those issues. Well, I don't know, maybe I guessed the intention of your question completely wrong. Good luck, David. _______________________________________________ Lilypond-user mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/lilypond-user
