From the manual I have learned that the Tyros has three foot pedal inputs. That's very nice....anyone here have a spare foot?

Seriously, this seems to be a "step" up (sorry) in terms of real-time control. That's always an improvement. I'm just waiting for them to develop brain-sensor technology (this exists) to the point where the musician can simply hook the keyboard to his forehead and sit back. Yes, it sounds ridiculous, but in theory it should be developed in time.
