You know when you think about it the QY-100 is really a pretty powerful little box. The unit is extremely small, and will fit on a keyboards music rack. It has an XG sound set with ability to tweek the voices. A total of 22 drum kits. It has preset styles and phrases,and allows you create your own. Good effects (customizable too). A 16 track linear sequencer with good editing (and it's internal). It also has an 8 track pattern sequencer. It has a micro keyboard on the panel for quick input, or you can use a controller. It also has a mic/guitar input with effects on that line. That alone is awsome. I can plug my guitar or mic in and jam to what I record. Plus it has smart media storage. I know there's a few features I'm missing, but all this for less than $500.00 You really can't go wrong with it. When I had my PSR-550, I'd always record my songs using the XG voices for backing and the panel voices for soloing. With the QY I can record my backing on it, and solo with my Casio WK-3500. Plus as my wife mentioned "the ability to record music while on the can" It runs on batteries and the adapter is less than $15.00 I'm fairly certain now that I'll be picking one of these up.
