Ok so i got my pcr300 on my last trip to the states in a samash store for a steal at $200! I got it home and of course had to download vista drivers but not much of a problem! I got it hooked up via its usb cable and i was set! I hooked it up and it just took off! i didnt need to set or program it! Although the keyboard does have an editor in which you can edit and set all of the controls on the controller to do whatever you want.
The keyboard itself has 32 velocity-sensitive keys, which have aftertouch, 50 fully assignable controls, 18 velocity pads, Keyboard split and layering unique crossfader feature, as well as nine fully assignable faders! All connections are on the left side - USB, MIDI IN/OUT plus separate Hold and Expression pedal ports. The PCR keyboard works with USB bus power. so you dont need an ac adapter.
It also comes bundled with cakewalk software the Cakewalk Production Plus Pack. which includes SONAR LE, Project 5 LE, and Dimension LE. Overall a brilliant user friendly controller!
