Gleix Video Synth // The I.F.D.

A self contained semi-modular audiovisual synthesizer for video feedback, digital glitches, drones and colorful experimentation

1_P1310304_Crop.jpg

The I.F.D., or Industrial Feedback Device, is an audiovisual synthesizer based around a no-input video feedback loop, video RAM and buffer manipulations, simple oscillator functionality, audio reactivity, CV implementation to allow easy integration into an existing modular ecosystem (esp. eurorack), and a visual method of building unique waveforms and sounds.

The I/O includes two composite video outputs, a VGA output, an external audio input (1/8” and 1/4”), and a standard 2.1mm barrel jack for a 5v power supply.

The originally beige enclosure was given an industrial theme and artificially weathered; the primary control panel was also given a circular brushed look.

  • On/Off button

  • RGB Mix knobs

  • RGB pulse buttons

  • LFO

    • On/Off

    • Rate, Shape, Depth knobs

    • Mode select (LFO vs standard oscillator)

    • Send switches for RGB channels

  • Image shift up, down, left, right, zoom adjustment buttons

  • CV control for RGB channels

  • CV/Trigger inputs for image shift up, down, left, right & zoom

  • 24 point patchbay for experimental glitches, routing audio in and out of the device

  • Amplified audio input, gain control, sends for RGB color channels

  • Composite video input & select switch (Added feature not shown in video)

  • Kill switch for up/down/left/right CV inputs

  • Custom CNC’d front panel and rear i/o panel

Commissioned by & custom built for Spike the Percussionist.

4/18/2021 update: The IFD came back to me for a few minor feature additions (kill switch for up/down/left/right CV inputs, composite input & select) as well as a CNC’d front and rear i/o panel - photos of the upgrades at the bottom of this page!

For a similar (but slimmed down build) with a bit of a vaporwave aesthetic, check out the 100PFB. Also, be sure to check out LoFi Future for his resources on creating a basic analog video feedback loop. This can serve as the foundation for all sorts of experimentation in DIY video synthesis.
