Theremin – Button activates Theremin. Your hand’s proximity to the top metal plate changes the pitch.
If the range seems wrong, turn on and off the device, making sure your hand is far from the metal plate or the top two metal rods.

Input gain – When a device is plugged into the INPUT jack, the theremin controlled ring mod effect is on. For guitars and quieter devices, turn this switch on.
The theremin button will turn off the effect and activate the normal theremin.

Loop – When on, the orange buttons will play until they are pressed again.
