I want a multi-flow project to have sections that each include several flows. I’d ;like to be able to insert uber-flow text frames that force the layout to flow around them. Is this possible?
I guess I could fake this by creating a new flow for each of the uber-flow titles I want and just change the text style and create an invisible staff.
No, it’s not possible for music to automatically flow around text frames. You would have to create multiple music frames that are manually positioned to take the text frames into account.
There is one single player holding a piano and the 0-line instrument from this post. The piano changes to the 0-line instrument when a system passes through the text frame and changes back afterwards. By using system breaks and carefully adjusted note spacing changes, the staff lines can be made to touch the border of the text frame on both sides. By using repeat markers, even the playback skips over the text frame.
Using hidden codas rather than the 0-line instrument makes it easier to align the gap in each system which passes through the text frame while continuing to have only one music frame:
Each coda to the right of the text frame uses the property Hide systemic barline to remove both the brace and barline, making it necessary to replace the barline with a vertical line. Each treble clef to the right of the text frame is replaced with the invisible clef, and each bass clef is replaced with the invisible bass clef from this post. The normal clefs are restored at the beginning of the next system, and a coda is added to hide the courtesy clefs at the end of the previous system.
