Re: Mensural notation: 2 questions

[Frauke Jurgensen]

Thank you, that first thing worked perfectly.

At the moment, I still have the parts in score (to check they're all at least the same length, which is a feature sadly missing in some of the manuscripts I'm dealing with). I'm bullying the ligatures into submission (such as when the second semibreve of a COP needs to be doubled to complete the perfection) using, e.g., \[ a1 b1*2/1 \] . This appears to work for the output I need just now, but I haven't yet considered the implications, should I wish to return to modern notation (at 1:1 note values).

Yes, that is the usual "we want quarter notes" mindset.
Use something like:

 % for the shown mensuration symbol:
 \set Staff.timeSignatureFraction = #'(3 . 2)

 % for the actual "bar" length:
 \time 3/1

As in mensuration sign + proportion, don't know to handle that.
Perhaps something like:

 \set Staff.timeSignatureFraction = #'(3 . 2)
 \time 3/1
 % some magic things to make two time signs to be shown
 \once\override Staff.TimeSignature #'style = #'single-digit
 \time 2/1
