HI AL,
I don't have a keyboard with a USB port. The PSR9000 is SCSI. The KN6000 does not have usb either
It sure works great on the computer. I put a bunch of songs in MIDI, and RA and a mp3 yesterday and then took it to a neighbor and plugged it into their usb port and played the songs. Awesome, I say Awesome!
