Sorry for getting a bit OT, Prelapse.

Rather than change your arranger, why not consider a Zoom H2 to record the keyboard? Instant, easy to use, immediate transfer (USB2 speeds) to the computer, mikes built-in if you want to record live audio... (MP3 playback if you use tracks)

To be honest, it's FAR easier to use and MUCH faster than the T2's built in recorder (and higher quality, too (goes all the way up to 24/96 .wav if you want!). Rather than trade away a great keyboard, perhaps this under $200 solution is what you need?
