Overview
Equal parts workhorse and abstract creative tool, Circa is a six track multi-layer looping environment that can do most of the things your popular floor pedal looper can while also paying homage to the serendipitous world of ambient looping.
Each layer can sync to the host, a master loop, or free run, and can be triggered in sync, with an audio signal, or freely. Circa has seven stereo outputs (including a dedicated cue output for monitoring) and built-in reverb and delay. Add in a complete MIDI control system and Circa is a full looping workstation.

Features
-
Multi-Layered Looping
Circa has six layers that can operate independently or in sync with each other and/or the host. Circa can record from the stereo input, or self-record via an internal buss for interesting feedback possibilities.
-
Designed To Be Touched And Played
Circa's user interface is made for tactile manipulation, with touch strips for speed and position (including dedicated pages). The position strip can be further subdivided with slices. All this works together to turn a looping effect in to a playable instrument.
-
Easy To Get Along With
Circa's layers each have an undo for destructive edits like recording, overdubbing, and erasing. In addition, product-wide tooltips make learning as easy as hovering. (Not available in iOS.)
-
Controllability
Circa has a full complement of true MIDI controller destinations. Use virtually any MIDI device to control most of Circa's looping features.
-
Self-Contained
Circa has a full internal mixer, filtering on each layer, and studio-quality send reverb, send delay, parametric EQ and compressor taken directly from Audio Damage's extensive effect library.
-
Expandable And Performance-Ready
Circa has 7 outputs in all: six assignable stereo outputs and a cue output for monitoring. Send any layer to any of the six stereo outputs, while keeping the cue for soloing, recording, and editing, unheard by the audience.
-
Ecosystem-Aware
In addition to drag-and-drop between the layers, Circa can drag its layers to the DAW or desktop. Circa's user presets are cross-platform compatible, and work on any instance of Circa, whether on macOS, Windows, Linux, or iOS.
