Critter & Guitari's description of the Critter & Guitari Rhythm Scope video synthesizer (Purple)


Overview: Rhythm Scope video synth.

If you ever wanted an audio-reactive video synthesizer, you have come to the right place!  There are three 'flavors' of Video Scope: the classic Video Scope, the graphic Rhythm Scope, and the monochromatic Black & White Video Scope.

They operate the same way: connect an audio source such as a synth, electric guitar, groove box, vocals, etc., and instantly see your sound on a TV, projector, or capture device! The only difference is the style of visuals they create.

The Mode knob sets the visuals while the Gain knob fine tunes the incoming audio signal to suit the imagery.

Drum Something: Rhythm Scope.

Beat sync!  Rectilinear graphics line up with incoming rhythms and arpeggios. For easy 'newness' the Random mode will choose a new visual pattern after a user-determined number of beats.
