May I add that I'm very pleased with the stability of my yampp3/usb. Works perfectly!
I honestly thought there'd be more problems with a "kit" like this, usb, firmware changeability, 3rd party HD and display. Very few.
Sure, there was a few minor snags before I got it up and running, and I think I got a few tunes I can't play,
but it's really nothing that bothers me.
I'm looking forward with exitement to the release of yampp9.
