Optotrem

Experience a rich and natural optical tremolo effect. The controls include: Rate to adjust the tremolo speed, Depth to determine the intensity of the effect, and Wave control that transitions from a square waveform at the minimum setting on the left to a triangle waveform at the far right. In between, you'll find a sine/rounded square waveform that incorporates a touch of asymmetry, reminiscent of an amplifier's tremolo.
