the 'light pedal' by gamechangeraudio would pair well with this. it uses a real spring inside the pedal to create an analog spring reverb. theres also some sort of laser used as well since the spring isnt long enough

there is also their 'motor pedal' which uses a spinning motor similar to one that would be found in a drone, and then a laser again or something optical to pick up the movement and turn it into a digital signal.

they actually have a synth that uses 8 of these motors to generate the sounds/voices
