The V-Shape is two modules in one, a wave twister and a distortion / wavefolding module. Both sections of the modules are all analogue in design, and both can be used independently or they can be normalled in series.
The wave twister can take (for example) a sawtooth waveform as an input and shape it, under manual or external voltage control, through to being a triangle waveform and on to being a ramp waveform, and produces a sound similar to pwm for sawtooths.
It functions according to the following mathematical formula: Output = min(In/CV, (Inverted In)/1-CV), where in In is the input voltage and CV is the CV voltage. It will produce an effect from most waveforms (with the exception of square waves), whether they are symmetrical or asymmetric. Under many conditions the transfer function is not perfect, so different harmonics may be generated too.
The second part of the V-Shape module is a distortion unit, with selectable Soft or Hard Clipping, and the clipping amount can be addressed either by a front panel control or an external control voltage. There is also a single stage, switch-able wavefolder, which can be used with either soft or hard clipped waveforms.
