oddly corrupt midi - need help

[Tom Cloyd]

My moderately small complete source file is here: http://pastie.org/7904566

I have two problems: a corrupt midi file, and a note head collision that I cannot seem to fix.

Two things to  note about the source: I am including articulate.ly, and this is set up to produce cross-voice arpeggios, not uncommon with classic guitar. The basic file structure comes from a guitarist who's been a member of this list in the past (I've basically been gone for two years), and has made major additions to the Lilypond documentation for classic guitar. I'm speaking especially of the code from "structure =..." on, which which frankly has always been a muddle to me.

1. corrupt midi file -

After upgrading Lilypond (at least one version), the midi file now get weird at m. 4. It SHOULD repeat, but in fact BOTH repeats AND plows on right through the repeat and plays the next line at the same time. Not exactly what I had in mind! I have no idea what's wrong, much less how to fix it.

Any help on this would be much appreciated.

2. note head collision that I cannot seem to fix -

In m. 12, at beat 2, there is an intractable (for me) note head collision. I've studied the documentation, and tried a number of things, and absolutely NONE of them have had any effect. Right now, there is in the code (l. 97) an attempt to move the top voice ahead of the bottom voice, which is split, at this point.

Any ideas how to fix this issue?

Thank for any help offered!

Tom
