"This particular Pro One has been fully serviced and everything is working as it should. On top of that, it's also been upgraded with the Techsmechs Fatar keyboard -- which seriously changes this thing into something extremely playable and musical. Really: once you've tried the Fatar keys on a Pro One you'll never want to go back to the j-wire version.

Somewhere along the road and over the years an owner added the buttons and switches you see above the mod wheels -- they aren't connected to anything, though. I looked pretty closely at the circuit board and as far as I can tell it doesn't seem like they were *ever* soldered to anything. Kind of fun to flick them back and forth, but that's about all they do. They're solidly installed, and don't negatively impact the synth -- just add a little flair and uniqueness to this particular instrument."
