I use this thang to get down ideas using the software instruments on Logic Pro. Very handy, compact, portable! Only drawback is that it does not seamlessly sync up with Logic Pro. Everything works EXCEPT the 8 little knobs. You need to buy Korgs software for full capabilities (which it does come with a "lite" version) but for me not worth buying the full version for, i think, another $300. Otherwise, I love the arpeggiator, little touch kaos pad, scale assign, and pads.
