Recent editions of the free notation software MuseScore have the ability to import MIDI files. This means, in principle, that I can export pieces I’ve written in Logic to MuseScore and put them online for anyone silly enough to want to play them. It’s a bit fiddly, but it does work with a little fussing, and I’ve launched a page at MuseScore for my sheet music. There are only a couple of pieces there so far, but there will eventually be more. Whether anyone finds them worth playing remains to be seen.
