Gravity Well

Tremolo / Wavefolder / Refractor

Cosmodio Instruments' "Gravity Well" is a submersible for exploring subaquatic psychedelic netherworlds of sound. It's a dual pedal featuring a tremolo on one side and a wavefolder on the other. When both sides are active a third effect emerges, a refractor, a first-of-its-kind style of modulation effect produced by integrating the tremolo and wavefolder to rhythmically and fluidly warp and un-warp your signal, producing a dazzling variety of never-before-heard sounds and textures.

Possibilities are endless, but include analog synthesizer sounds, touch sensitive envelope filter-esque sweeps, heavy cinematic pulsing rhythms, splatty gnarly alien fuzz, ring mod like bell tones, science fiction sound fx and textures, and surfy tremolo warbles, just to name a few!

Tremolo (right side) - A classic effect achieved by modulating the volume of your signal. Most commonly associated with surfy 60s vibes, it can be pushed towards ring modulation or shaped into heavy rhythmic effects.

Wavefolder (left side) - An uncommon effect in which harmonic overtones are added to the input signal by folding the wave over itself, back and forth, to create new pitches and frequencies. The result can be synthy, squishy, splatty, funky, dirty. Extremely responsive to your playing and to your instrument’s volume knob. 

Sonic Refractor (both) - When both sides of the pedal are active an entirely new type of effect is born . The movement of the tremolo interacts with the wavefolder to fold and unfold sound waves, dynamically warping your signal. Achieve anything from harmonic tremolo, to alien phasery univibey shifting, to analog synth and sequencer sounds, to pure out-of-this-world science fiction sound effects and textures

SPEED controls the rate of the tremolo and/or refraction.

DEPTH sets the depth of the tremolo and/or refraction.

FLOW determines whether tremolo sits before or after the wavefolder. This dramatically changes the behavior and sound when in Sonic Refractor mode, when both sides are active. Signal flows in the direction of the switch:
•Left: tremolo > wavefolder
• Right: wavefolder > tremolo.

WAVEFORM selects between eight different modulation shapes: sawtooth, ramp, square, triangle, sine, swoop, sample-and-hold, and random movement. Start with triangle or sine for traditional tremolo, sawtooth or square for staccato rhythmic effects, ramp or sample-and hold for sci- vibes, or swoop or random movement for asymmetric experimentation. Get creative. Depending on other settings these different waveforms can push Gravity Well into completely different aesthetics.

EXP/TAP allows an external tap tempo switch, expression pedal (TRS), or control voltage (CV, TRS, 0-5v on ring) to control effect parameters. Can be configured via internal DIP  to:
•TAP (default) - Multiple taps sets tremolo SPEED. A
single tap restarts tremolo waveform phase. [Requires a
normally open TS or TRS tap tempo.]
•SPEED - fluidly control tremolo speed via expression/CV
• DEPTH - fluidly control tremolo depth via expression/CV 

VOICE selects between 3 different flavors of the circuit. This control is highly interactive with the other controls, especially the Gain knob.
•Center: Full spectrum wavefolding. Gets crazy real fast.
•Left: A low-pass lter before the folding stage keeps wavefolding focused on fundamental pitches. Darker at lower gain settings, but more focused at higher gain settings.
• Right: Mixes a clean-ish signal with the wave folded signal for clarity, balance, or to preserve bass and transients of the unaffected signal.

GAIN amplifies the input signal being fed into the wavefolder. In the same way more gain causes overdrive effects to clip harder, more gain makes a wavefolder fold more aggressively resulting in a stronger effect.

TONE selects between a dark, balanced, or bright output.

VOLUME controls the output level of the wavefolder.
