Twenty-Three Octave multi-mode voltage-controlled oscillator

Sinc Iter is a four-HP voltage-controlled oscillator with a 23-octave range. It has three waveform modes: noise, plain, and super, each of which allow continual morphing between waveforms. Front-panel unipolar and bipolar outputs allow for easy use as a control source. Phase modulation and Sync modulation are both supported to provide maximal tonal variety. The Sinc Iter also has a built-in quantizer.
