The Cosmic Instruments Wavetable VCO is a versatile Wavetable oscillator that provides both a main oscillator and a sub-oscillator. Both of these oscillators can be controlled using a variety of different parameters. To get a sense of what the module is capable of, we have outlined the functionality of each knob and input jack below. Knobs: - Freq, the frequency of both the main and sub-oscillator. The sub-oscillator usually has a frequency that is either one octave above, one below or two below the main osciallator's frequency. - Shape, changes the soundwave of the main oscillator. The 16 selectable soundwaves range from smoother sine-like sounds to more complex sounds with lots of harmonics. - Fine, same as the frequency knob, but allows for more finer control over the frequency. - Sub, changes the waveshape and/or octave of the sub-oscillator. There are 8 soundwaves to select from, plus an octave up, octave down and two octave down option for all of them. - Glide, instead of the oscillator jumping from one note to another, the glide functionality allows for sliding between notes. - Bitc, short for Bitcrush, which allows for reducing the number of bits, which adds some nice roughness to your sounds. Inputs: - Freq, voltage control for the frequency. - Sub, voltage control for the sub-oscillator's shape. - Wave, voltage control for the main oscillator's shape. - Voct, voltage per octave control for the frequency. The module needs to be callibrated using the blue trimpots at the back of the module first. - Sout, audio output of the sub oscillator. - Out, audio output of the main oscillator.
