I found the link because I was curious if player piano rolls could record live playing. Yes.
What sparked my curiosity is 21 Pianomation Floppy disks that arrived yesterday with a recently eBay’d Yamaha Midi Data Filer 3. Pianomation is a system QRS corporation fits on grand pianos to allow them to operate as player pianos.
QRS is still in business and started out making piano rolls around 1900 and quickly invented a machine to record pianists live performances. https://www.qrsmusic.com/
Anyway, the floppy disks are approximately album length collections of Midi files and quite a few of the Midi files say who played the piano. Given when some of the players died, the Midi is almost certainly converted from piano rolls.
I’ve been playing them back through a Yamaha General Midi era piano voice…and $10,000 hands on a two dollar guitar surely does sound better than two dollar hands on a $10,000 guitar.
But Liberace might be spinning in his grave…I ran his data into the Honky Tonk Piano.
I love this background information. I hope you’re backing up those MIDI files!
Probably not.
I expect to test the rest of them…I suspect they all work…then resell them on eBay.
Backing up data is not a hobby that interests me, hard copy rolls exist, the company is still in business, and the files are still under copyright.

At 10000 rpm, not one less.
Not 78?
