A few things about myself. I'm a serious hobbyist. I just play for myself ... no gigging, no singing. So stand-alone playing experience is what matters most to me. I don't like to hook up my keyboard to a PC, so lots of cool styles and accompaniments will be a big plus (which I beleive roland offers). And although i mostly play western style tracks, i may be interested in oriental stuff since i'm from South Asia (thinking about EXR-40 OR too).
