I have a large computer music generating program that I'm creating. One of the things it does is generate sheet music for the generated music using Lilypond. It works really well.
When dealing with one or two voices everything's fine. But I just added a musical style that uses three voices and collisions with rests are occurring. The Lilypond files are generated automatically by my software and cannot be hand-tweaked afterwards (end users won't know how and shouldn't be expected to do this anyway). In other words they need to be perfect or at least good enough. Options I've added to the software: 1. Eliminate all rests for quiet voices (which can look weird but is kind of neat). 2. Use the \rest option. 3. Use spaces instead of rests. Here's the thing, using any, all, or none of those options at one time might result in a score without collisions but when I change the instrument or just run through it again with different data there might be collisions again. These are blunt tools that cannot be used selectively on certain notes -- it's either all or nothing. So what I'm wondering is if there are any other strategies people have for automatically avoiding rest collisions and if this is the sort of thing that might be dealt with in the future in Lilypond or if maybe it's just too difficult a problem for Lilypond for now? I haven't supplied an mwe (though I will if someone really wants one) as my software generates infinitely many scores so a solution for one score won't necessarily work for another which is why I'm seeing if maybe there's an approach that I'm not aware of.
