Audya Rotor by sustain-pedal

Am I mistaken? I really thought that I could use a sustain-pedal for changing the speed of the rotor, not as a switch but with a hold-function. That means, if I press the pedal the speed will be fast, if I put my foot away from it, the speed will be slow. Is there any way to settle the rotor-speed that way? Thanks for any answer.

Hi, I don´t think so...

With a "normal" switch no problem ( I use it that way ).

BTW: You can change the rotor-speed using the stick up/down ( should be modulation wheel on "normal Audya" ) in more than one step ( not only slow and fast, 2 speeds in between )
