TL;DR
How do I engrave an alternating time signature and an initial cue clef?
Scriabin has a prelude where he has written a time signature as alternating 5/8 and 4/8 time. After the initial one, no other time signatures are written. I have figured out a way to engrave this with help from a LSR entry.
Also, the first notes in the right hand are in bass clef. I want to engrave the initial clef in the right hand as treble, then after the time signature have a cue bass clef. Lukas-Fabian Moser wrote a solution for that (thanks!)
The problem is those two solutions don't work together. (Looking at them, I can see why they wouldn't.) I am not clever enough to merge the two solutions or think of a third. Can anyone help me?
I've attached a screenshot of what I'm trying to engrave. Also attached is my attempt to use the two solutions, but without success.
