Hi David, What does usable-duration-logs mean? The NR internals section says: usable-duration-logs (list): '(-3 -2 -1 0) List of duration-logs that can be used in typesetting the grob.
This says which rests can be used for a whole measure (depending on its length).
-3 maxima -2 longa -1 breve (that’s default for 9/4 time) 0 whole/semibreve 1 half/minim 2 quarter/crotchet 3 eighth/quaver …Normally, you wouldn’t use positive logs (rest durations shorter than whole) even for shorter measures like 3/8. But longer measures like 4/2 or 9/4 will get longer rest durations because negative logs are allowed. Setting usable-duration-logs to '(0) allows only whole rests for measures of all lengths.
