A Universe of Scape-inspiring Ambient Reverb
Whether you’re filling an opening on your existing pedalboard or seeking an incomparably cool ’verb to spatially expand your synth setup, the Cosmosis I stereo ambient reverb pedal is ready to fill that space. Literally. A down-sized take on the original Cosmosis pedal, the Cosmosis I affords musicians nearly all the same spatially creative features in true digital hi-fi quality, but with a smaller form factor. Design and save up to three ambient scapes of any size from three space-type starting points: Theater, Temple, and Cosmos. Blend your signal’s wet/dry balance, shape its Tone to taste, and easily enlarge or reduce the Size of its boundaries. The press-and-hold Morph function reappears, equipping you with mesmerizing real-time parameter control. Intuitively blueprinted with color-coded custom LED touch switching, it’s a breeze to make sense of your settings mid-performance, too. And of course, Sweetwater players love its stereo availability through the TRS output to vastly expand the potential of your space at hand!

Powerful 3-verb solution
A trio of incredible reverb algorithms help set your ideas in motion, starting with Theater mode. Identified in blue, Theater uses parallel short reverberators to form a room-like setting with the flexibility to expand from close-quartered coziness to larger, more reflective spaces. Temple mode takes this idea further, with an amber glow that accompanies the effects of huge indoor settings through longer reflections in series and parallel. Finally, the purple-tinted Cosmos mode blasts reverberative borders wide open, using derived harmonic information to create inspiringly expansive results.


Expressive morphing power
In addition to its knob-controlled Size, Blend, and Tone parameters, the Cosmosis I offers even greater creative potential for crafting the perfect effect you envision. Enter the Morph function: a Pigtronix specialty that gives users the press-and-hold convenience for gradually altering multiple parameters in real-time during performances. Assign a red or green value to each parameter, then begin morphing the parameter in question (as indicated by the “engage” LED) with a simple press of the footswitch. Minutely morph and sweep or generate enormous shifting atmospheres to best suit your tune — you’ve got total control!
