CONTROLS
Rate
The rate control, controls the speed of the tremolo. On the Stereo Semaphore this knob’s characteristics are affected by the position of the Tap Divide control. If the Tap divide is set at a higher rate, you will notice that the Rate knobs sweep will change as well. The expression pedal nullifies the rate control when plugged in.
Tap Divide
The Tap Divide works as the engine for the Tap function of the Stereo Semaphore. Since a tremolo can obviously operate at a much faster rate than one could tap out, this control takes your tap tempo and multiplies it by the corresponding note beats. The quarter note represents the same tempo that you tap out. Once a tempo has been tapped in, the Tap Divide can function as an in-time rate control.
Shape
The Shape control is used to morph the selected waveshape. At noon your waveshape will represent the shape on the Waveshape control, but to either side this shape will slant providing numerous sounds and endless possibilities. The Shape, however, has no effect on the Random waveshape setting, because it is random.
Waveshape
The Waveshape control provides eight different waveshapes, which won’t leave anybody wanting for more.

Depth
The Depth control dials in how much tremolo is in your signal. Dialed all the way down, the Stereo Semaphore can be used as a boost, and you can bring up the depth enough for slight shimmers in your signal, or all out depth, for maximum effect.
Volume
The Volume control, obviously, controls the volume of the pedal. Unity on the pedal is around noon, depending on the voltage running, and provides plenty of boost or attenuation.
