Thanks, Chris. I have read that discussion, and also on Mudcat, and I am not satisfied yet. Abc to MusicXML should be among the easier tasks to program. To buy yet another gigantic piece of software only for that task seems grotesque overkill.
To give a good example, I have published my own tool MidiZyx2abc as freeware (http://www.midicond.de/Freeware/index_en.html
, I'll write about that on another thread). We must join forces, so now it's someone else's turn. Who shouts "here"?
