Be sure to add me to your favorites list Yamaha CBX-K1 MIDI Controller Midi XG Original Owner's User's Operating Manual Book. This is an original Yamaha User's / Owner's / Operating Manual for the Yamaha CBX-K1 Midi controller keyboard. It's in very good condition with some wear on the covers, but not much on the pages themselves. There are English, French and German sections ... Very helpful if you have a CBXK1 keyboard, especially if you plan to use it with any Yamaha XG midi instrument, keyboard, synthesizer, tone module, sequencer, sound card other unit. This is a manual or document, this is NOT a piece of equipment or instrument. If you have any questions, I'm always happy to answer them. Thanks for looking! Check out my Store!
