Purchased in late May of this year. I am selling it because I upgraded to the Quantum HD2 and no longer need it. The firmware has been updated to the latest version. Since the serial number is unregistered, Studio One Pro V7 and other software can be used. By the way, the new price is 32,800 yen at SH, and it is a made-to-order item.
