Hammond XK-3C, triggering vibrato/chorus with footswitch

[Guest]

Does anyone one know how vibrato/chorus on an XK-3C could be triggered by the Hammond footswitch or the lever on the EXP 100F expression pedal or by some other means (advanced configuration)? It would be nice to turn the vibrato/chorus on and off without having to take a hand off the keyboard.

The documentation states that only the leslie effect, damper effect, presets (up or down), spring reverb and delay time can be triggered by the footswitch or the lever on the EXP 100F.

I suppose I could mess around with the presets, having two similar presets, one with chorus and one without but that seems clumsy since you can only go in one direction when using the footswitch to change presets.

The "User" button and the assignable buttons can be used to trigger the vibrato/chorus but they also seem like they can't be controlled from the footswitch.

I suppose the assignable buttons are my best bet since they are closest to the keyboard and can probably be pressed with the least interruption of play.

Thanks!

You could connect 2 footswitches by using a Male TRS to TS/RS Female Y cord and have one do preset up and the other preset down. The Preset load parameters (Pg. 58) may be useful by allowing you to turn some of what gets loaded when you change presets. For example you could set it so that only Vibrato, Overdrive and Leslie settings (#9) get loaded. Preset load parameters are Bank Parameters except for Link - Lower/Pedal (#3) which is Global.
