The Master Oscillator is the central nervous system at the heart of the Data Corrupter’s cyberpunk hive mind. It feeds your input to the signal harvester in its original octave (Unison), one octave down (-1) or two octaves down (-2) for maximum compatibility with your preferred instrument and frequency register. Once you’ve chosen your input octave, then the Data Corrupter will perform its calculations and spit out an analog synthesized frequency, which can be pitch-bent for portamento or vibrato sounds by the Frequency Modulator! From there, you can blend in one of eight Subharmonic intervals up to three octaves below the input and mix in a square wave fuzz tone for maximum data corruption.

Design Notes

This device takes its inspiration from the Electrax Synthax and the “Basic Frequency Synthesizer” by Ray Marston. Neither of these were really intended to be guitar effect pedals and a lot of work went into creating the Data Corrupter to provide excellent tracking and long sustain. We think you’ll find it more expressive and accurate than pretty much any other PLL based effect pedal around.

The heart of this pedal is based around a CMOS Phase Locked Loop (PLL) IC. In a nutshell, the PLL takes your input signal and compares its phase and frequency against an oscillator, generates an output proportional to their difference then feeds it back to the oscillator. This then causes the oscillator to lock onto the input signal and generate a synthesized frequency. Pretty cool, right? This synthesized frequency is referred to as the Master Oscillator on the Data Corrupter.
