You can go to Options->MIDI, and set Sustain pedal to respond not to Controller 64, but Controller 1 (if that's the controller that's controlling Leslie speed on your XK-1).

Granted, it won't be continuous. But you'll have your sustain functioning.

Hi,
I assume I can run Pianoteq on my new Hammond XK-1.

But the pedal-function on the Hammond is to switch the lesley effect on or off. Do you think I can overrule that function of the pedal via my laptop and make it a sustain pedal for piano?

Thanks, Thomas

I just skimmed the manual and it seems you can choose the foot switch's effect inside the keyboard, but I think there is always a Control Change 64 being sent via MIDI which is exactly what Pianoteq needs for the Damper Pedal.
