MUSICAL FEATURESAthru is a compact and full-featured wave folder. The wave folder that makes the waveform larger and folds back from the time when it exceeds a certain size can control the folding amount with the slider and CV with Attenuverter. The Athru has a second signal input (bottom right of slider, with attenuverter) that, when patched, mixes the input signals before passing through the folding circuit. 2V is internally connected to this input when not patched by turning on the "Bias" switch. Therefore, if you move the Attenuverter from 5 in this state, the signal patched to the first input will be offset up and down, and you can further change the tone by passing through the wave folder. The input can be overdriven with the Drive switch.
The main wave folder can be used like a VCA because the volume becomes 0 when the slider is moved to the bottom. The lower left jack is a trigger input, and when a trigger is input, the amount of folding can be modulated with the built-in envelope (decay can be adjusted with the knob on the back of the board).
