Selling ain very good condition.Very minor scuffs, all buttons work great (and don't stick!), and I just replaced the internal battery. The battery compartment is also in good condition (no corrosion) and can still be used (I recommend rechargeable batteries). The LCD works great, and no dead pixels.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. It makes an excellent sketch pad for ideas, and actually features fairly flexible sound editing.

This sequencer is very light and compact, about the size of a Sega Game Gear, and sports a 16-track sequencer with 519 voices and 20 drum kits, auto-accompaniment capabilities, and a small keyboard that you can use to program patterns and songs. The sequencer also allows step editing for very complex programming. It also features DIN MIDI in and out, so you can sequence external gear from it as well.
