Thanks for any help you >can offer. >- I'm not a scheme programmer either but we do have a snippet http://lsr.dsi.unimi.it/LSR/Snippet?id=333 That might give you some clues. I am also guessing that you could use a similar method that we document for 'Upbeats' (see Notation Reference) where we can use \set Timing.measurePosition blahblahblah (instead of \partial X) to denote a position in a single measure but for your specific case use \set Timing.internalBarNumber or \set Timing.currentlBarNumber somehow. Look in the Internal reference for Timing_translator. I'm throwing these ideas out so that if you cannot figure something out, someone else more knowledgeable that I in the internals might.
