Wave Function

The Templo Devices Wave Function Tremolo is an all-analog optical tremolo with extensive control over the modulation waveform. Speed sets the modulation rate, Depth controls the amount of volume attenuation, and Shape selects square or triangle-wave modulation. Ramp changes the transition between the on and off portions of the waveform, while Symmetry adjusts their relative duration for different rhythmic pulse shapes. A dedicated Half footswitch can halve or double the modulation speed while maintaining the tempo; holding it gradually slows the tremolo to a stop. Follow mode responds dynamically to the input, pausing the tremolo after a strong note and bringing the modulation back as the note decays. The pedal uses LED-based optical control, soft-touch switching and buffered bypass.
