Me neither. I wanted The Doug to write a lex/yacc one, but he refused :)

The reason we used that format is that it's what comes out of scala, see http://www.huygens-fokker.org/scala/scl_format.html For the moment we only distribute 12-ET and 19-ET files, because all the microtonal performances we're working with are singing or playing in 19-ET, but there was a time when we were considering extended mean tone. Because tuning's a very sophisticated and difficult area as soon as you move outside equal temperament, we thought it better to use scala to generate these values. It's easy to work out n-ET with appropriate use of pow(3), but what about "1/4-comma meantone scale. Pietro Aaron's temperament (1523)"? I suppose an scala to rosegarden tool would be possible, but I'm opposed to that because it constitutes supporting scala which, although ubiquitous among the micro-tonal community, is non-free. The parser we've got is nasty, but self-contained and quite well-tested. The only real thing I've got against an XML one is that it gives me the opportunity to introduce a whole new raft of bugs, many of which would be hard to detect.
