I have been using Musescore from pkgsrc for a while. I also have a Debian machine (because it has an inbuilt video card that doesn't like NetBSD) with which I use an older version of Musescore (Debian package manager). That machine has an attached MIDI keyboard for score composition. (I don't like entering notes and especially chords with the mouse).
Recently I did some rearranging and connected an old NetBSD machine (Pentium 4) to a better-suited piano, for score composition. Now I can get MIDI events by other software, but not Musescore. I had to rebuild Musescore with ALSA support just to get the MIDI Note Input option to turn on. I also tried Jack, which sees the piano, and Musescore, but I still get no MIDI events in Musescore.
Has anyone else gotten this to work? I hate to have to resort to Debian again.
