YAMAHA QY70 Music Sequencer XG new internal battery!! w/ box

The QY70 is a small but sophisticated "all in one" musical unit, providing all the necessary parts needed to record complete songs: a sound engine, sequencer, effects, even pre-made patterns and fills that you can also modify or create from scratch.  This device has been the weapon of choice for many bands, including the great synth-pop act Freezepop, that features the little grey wonder as the base of most of their electronic songs.

This little music sequencer is very light and compact, but sports a 16-track sequencer, a high-quality tone generator with 519 voices and 20 drum kits, advanced auto-accompaniment capabilities, and even a small keyboard that you can use to program patterns and songs without having to hook up an external keyboard via MIDI.  Add the fact that this unit can be also battery-operated, and you'll agree that the QY70 is a perfect tool for the performing artist.
