Original Yamaha QY20 Midi Data Format Booklet, Original Yamaha 20 Page Document, Made in Japan
This is a supplemental owner's manual from Yamaha. It's the Midi
Data Format booklet for the Yamaha QY-20 music sequencer. It's an original document from
Yamaha and has the very detailed MIDI data not found in the main QY20 manual.
This book is 20 pages and in very good condition, with many of the pages themselves being closer to like new shape. From the early 1990's, extremely useful if you want
to know everything about the 2nd QY model!
