Circa runs as a standalone app, or as an AUv3 plugin in hosts such as GarageBand, Logic, AUM and Cubase. 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 and LFO modulation 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. -- Standalone Or Plugin As a standalone app, Circa has its own audio and MIDI settings: choose your audio interface, sample rate and buffer size, pick the input pair, send each of Circa's seven outputs to any output pair on your interface, and select a MIDI input. Sync to incoming MIDI clock, or let Circa set the tempo from your first loop. As an AUv3 plugin, it lives inside your host and syncs to its transport. -- 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 into a playable instrument. -- Easy To Get Along With Circa's layers each have an undo for destructive edits like recording, overdubbing, and erasing. -- Controllability And Modulation Circa has 30 modulation slots. Each one can map a MIDI controller to any of Circa's looping functions, or run an LFO: seven shapes, free-running or tempo-synced, with rate, phase and level, modulating speed, start and end position, level, panning, delay and reverb sends, filter frequency and resonance, or the slice the play head is on. LFOs swing around wherever each control is set, so the knobs stay in charge. -- 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. In the standalone app, each output can go to its own pair of outputs on your audio interface. -- Ecosystem-Aware Circa's user presets are cross-platform compatible, and work on any instance of Circa, whether on macOS, Windows, Linux, or iOS. In addition, sessions created in GarageBand or Logic on iOS will open in the desktop version on macOS if you have purchased a license to that version.
