Ya, the Kindle page-flip will not work with the Bluetooth page turner.
This may not be relevant but I have a work-flow (for work OR for a cookbook) that I use all the time, although I’ve never used it for a book of printed sheet music (yet!).
When I require either:
1/ a book that lies flat, aka spiral-bound (e.g. cookbook, music scores in bound books) OR
2/ a digital copy of a book that is only available as a paper printed version
I order the paper book
When it arrives I take it to the local ‘copy shop’
For $1-2, the copy-shop folks slice the binding off for me and replace it with a spiral-binding. So cheap!
I take the stack of now-individual sheets home (without binding) and
feed the stack (“the book”) through my fast document scanner
This device scans individual paper sheets, front and back, at 50 pages/min and simultaneously digitizes the context, then saves the stacks of sheets as a single PDF to my Mac laptop… and it does this all wirelessly! of course, it also gives you the option of saving each page as an individual PDF. The scanner also ‘instantly’ converts any text on the pages (titles, composer) into readable- and searchable- digital text. And the quality? super-duper crystal-clear. Excellent!
I have a ScanSnap sheet scanner— dang expensive ($400?), but it was purchased for work and was one of the most useful home office purchases of all time, imho: https://www.fujitsu.com/global/products/computing/peripheral/scanners/soho/
… anyway, scanning done:
Sometimes, I return to the copy shop after the scanning is done and have them complete the binding (spiral), so I have the paper original in an easy-to-store format.
Anyway, I suppose that most people won’t have a fast scanner at home but perhaps it’s not too expensive to have the copy shop do that task as well?
This all sounds long and complicated but it’s surprisingly easy:
I just drop the bound-book off and pick up the new-improved spiral-book when it’s ready.
Naturally, a digital copy from MusicNotes, etc. is the easiest path of all— if you can find one.
