Comment #3 on issue 3003 by address@hidden: Document the MIDI  
backend
http://code.google.com/p/lilypond/issues/detail?id=3003

Don't worry, Trevor, I am still on it. See the links in comment #1 to track  
my progress.

My attempt to make sense of David's comment made me start to work on  
disentangling the layout and MIDI context hierarchies. As a result, in my  
opinion, the code crossed a complexity threshold that made it worthwile to  
also clean up other parts more extensively.

So I decided to work on my own branch "doc-ir-rewrite" for now, and to  
prepare a more complete patch set (or a merge offer) later. Since my time  
for this is limited, I have to ask for a bit of patience.

[Re-reading David's comment, I think I only now quite understand what he  
meant; the "engravers also used as performers" really threw me off. It is  
somewhat unfortunate that we could not sort this out earlier, and I may  
come back on this on Rietveld, but anyway I believe the direction I have  
taken makes sense.]
