    What Do Fairfield Circuitry Say?

    "What we have here is a failure to communicate"

    Inspired by Roger Grant's idea to mimic loss of fm radio signal through the use of a simplified fm modulator/demodulator scheme.

    As a young child, I would hide under the table when Roger came around. Later, when I first started in electronics, he gave me a bunch of parts, tools and bench equipment.
    Controls interfere with demodulation accuracy resulting in familiar yet unexpected signal degradation and noise.

    While it is true that RF is especially effective at professional noise making, it remains relatively safe for amateur producers.

    Controls interfere with demodulation accuracy resulting in familiar yet unexpected signal degradation and noise.



    Like turning the dial on your receiver, the TUNE parameter sweeps through a wide variety of sounds. From subtle artifacts, to extreme textures, noise and distortion. Summmed with CV at T input.


    Shifts the accuracy of tracking the incoming modulated signal. Sometimes acts as a filter. Highly dependent on TUNE.


    Controls the input level, from clean to dirty. Pushing the DRIVE control generates extreme non-linearities from the modulator/demodulator circuit. Affects both the wet and dry signals.


    Amount of wet signal at the output.


    Amount of dry signal at the output.


    Preset range of the TUNE parameter:
    1 - normal
    2 - extended


    Apply voice filter ~(300Hz-3kHz) to wet signal:
    0 - filter off
    1 - filter on
