The controller "Bypass" adjusts the AM-Input ↔ / -oscillator output ratio. Fully clockwise:
The / -oscillator output is 100%. Fully counterclockwise: The / -oscillator output is 0%,
AM-input ( ) is 100%. Thus, the original to the "effect" signal can be mixed (≙ "dry/wet") when the
oscillator is used as a ringmodulator, or for modulation options when it is used as a CV-source.
The output voltage range of the / -oscillator is adjustable with trimmer
