oh, interesting. but that makes the pieces of informations fit together! >> Graham sent me an example, but 2.13.51 couldn't >> compile it. I want to work on that too. > > That's a shame.

I think now I understand the issue: MIDI signature must be a conventional one in equal temperament - is this true? then your patch is obviously ok. p _______________________________________________ lilypond-devel mailing list lilypond-devel@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-devel
