A version of Morphing Organ drone showing how to turn the drone on and off using pedal control.
See Morphing Organ Drone for details on Macro Controllers.

Instructions:
No fingerboard or Keyboard used. Drone will start when you press switched pedal down and stop when you release. Make sure you have a pedal supported by Continuum or Osmose.

Other drones can be adapted like this. See formula J that is tied to a Macro controller (v) here. When pedal is pressed Macro Controller goes to 1 and that then is used as a SL/SR multiplier to turn on the output. When pedal is not pressed the output is basically multiplied by zero and hence no sound.
