Feedback Sine


This Sine wave oscillator feeds its output back to its phase input on a 1-sample block, creating very bright spectra that reach the limits of noise! All aspects can be CV controlled

Feedback Sine is a VCO (Voltage Controlled Oscillator). It is a sine wave oscillator with integrated phase modulation. It feeds its output straight back into its phase input, to add harmonics for creating more brilliant sounds. The feedback happens on a 1-sample block, so you can get a sound as bright as possible, without having a full sample-block latency.

Even though phase modulation happens internally via feedback, external phase modulation is also possible by inputting a signal to the phase inlet. If the incoming signal is a phasor and not an oscillator, instead of phase modulation the oscillator will do phase syncing with the incoming master phasor! Syncing can be either hard (the oscillator resets is phase when the master oscillator starts a new cycle) or flip (the direction of the oscillator flips when the master oscillator starts a new cycle). The two syncing modes can be cross-faded with the “SYNC” potentiometer, or with a CV signal in the “SYNC” inlet.

A three position slide switch sets the frequency range of the oscillator, making it a high-range, mid-range oscillator, or an LFO!

Three outlets are included in the panel, one for the bipolar oscillator signal, one for a unipolar version of the oscillator, so it can be used as a CV signal, and one for its phasor, so it can act as a master oscillator, syncing other oscillator modules!

Note that you must have one MAIN module in your system!
