Odd time signatures, cross-screen
I'm doing odd time signatures by setting odd track lengths, e.g., for a 7/8 piece, a one-measure track is shortened a half-beat from the default to 14 16th notes. This gets awkward for longer tracks, where (at the default zoom level) the second measure starts on the last two columns of the first screen, the third measure starts with the last four columns of the second screen, etc. This also makes cross-screen useless, as screens no longer align with a consistent musical unit.
Is there a better way to do odd times? Is there a hack for getting cross screen to be as useful for a track in an odd time as it is for common time?
