Also, for fun, Herbie Hancock explaining a CMI to David Letterman. Around 4:50 if the link acts up. https://www.youtube.com/watch?v=5QQgZmu4hZ0&feature=youtu.be...
Chances are good the floppies are part of the original sample library, which is widely available.
The three disks are labeled:
1) "Ultranox drum sounds, Simmons Drums Sounds, Tom Severetts Drum Sounds"
2) "Freddie Perren's Drum Sounds"
3) "Audio Disk: Vic Coppersmith / Europeans"
All three disks are BASF 128 Bytes(!), 25 Sectors.
If you can point me in the direction of those original sample libraries I would be appreciate it, as it gives me a space to start parsing these!

Edit: The website is also spruiking a $50 app which appears to be based on the original CMI source?
