Description
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. Decoherence at its finest.

TUNE:
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.

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

DRIVE:
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.

WET:
Amount of wet signal at the output.

DRY:
Amount of dry signal at the output.

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

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

CONNECTIONS:
IN: 1/4" Instrument input
OUT: 1/4" Output
T:1/8" CV input for TUNE
9V: 2.1mm 9VDC centre-negative tip, >30 mA

NOTES ON INTERACTIVITY:
  • The TUNE, SHIFT, DRIVE and RANGE controls are highly interactive.
  • The higher the DRIVE, the more artifacts will be generated.
  • TUNE is probably the widest, most non-linear, finest control ever included in our products. Micro adjustments here will drastically change the result of the demodulation.
  • TUNE and SHIFT are mutually dependant, almost like they are the same control. By tweaking both, it almost seems like there is endless varieties of sounds.
  • The RANGE switch shifts the whole palette of possibilities.
  • Wet signal path is intentionally out of phase allowing for special interactivity between WET, DRY and FILTER.
  • If the original signal is still present on the wet side, adding dry signal will cancel it out leaving only the distortionartifacts.
  • If voice filter is activated in these same conditions, the result is a kind of mid-scoop instead of the usual bandpass.
