The Yamaha QY 700 is a music sequencer from the 90's! So, it is a DAW from the past! Use your MIDI cables to connect it to your keyboard with MIDI ports, and lay down tracks like drums, bass, keyboard sounds, and much more. It has a ton of rhythm tracks ready for you to play as soon as you turn it on! It has a nice big screen that makes recording tracks very easy! I used mine for a long time, and even after the computer-based sequencing programs (apps) came out. I did a show as a "one man band" for several years, and this is the only sequencer I ever used. The unit has too many features to describe here, but there are some great YouTube videos that explain exactly what it will do. It comes with a hard case, power supply, and manual. Asking $400, or best offer. Please do a little research on it before you call, so you have a good idea what it can and will do! Will consider trade for a high-quality acoustic guitar like Gibson or Taylor. Please call or text Daniel for more information. I will have more photos and much more information on this in a few days.
