Diki what you say is true. I have used foot conrrollers for years, in fact made my own for the Roland! Had the 13 sw pedal for the SD1. For me the switches are all too close togther. In fact on the MFC10 if you hit the 10X button by mistake .. your screwed!
Maybe it's just me but with the PA2x I have finally made up my mind to use other methods to trigger things. Now I use the velocity to trigger the Break/fill and it works great (saves a switch on the FC5) Set Sw 1 for Fill 1 and Sw2 for Fill 2. Sw 3 for the Harmonizer. Use the Joystick for Leslie slow fast. I am saving sw 4 and 5 for Articulation control when OS2 is released. Also I have set it up so Fill 1 advances to variation 2 Fill 2 will advance to variation 3 fill 1 will take me back to Variation 2. It may sound strange to some but it works for me. I like the Yamaha method the best... fill to variation but that is the only plus in my book and not enough for me to give up the PA2x.
