Hi all, I'm working on a graphical music editing program. The final output (with Lilypond, of course) is going great, but for editing the music in real-time it's way too slow. Can you give me advice or point me toward a resource on speeding up Lilypond by turning off features? For instance, I don't care about stem length, beam slant, collisions between noteheads and anything else, collisions between markup elements, or spacing between staves. And since it will always be rendering to a single page wide enough to hold it all on one line, I'd like to turn off the line break calculations. What do you suggest?
Hi Isaac,I hate to be the bearer of bad news, but LilyPond doesn't seem to be the right tool for real-time engraving. Maybe take a look at guidolib (http://guidolib.sourceforge.net/), which is specifically intended for real-time engraving. INScore (http://inscore.sourceforge.net/) is a very cool environment that employs guidolib for animated, interactive scores.
