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.

"A deep world to get lost in - This delivers that in spades!" - Jamie Lidell, Hanging Out With Audiophiles Unfiltered Audio is back on iOS with its instant classic Battalion, perhaps the most advanced drum machine available on any platform. Battalion includes over 20 synthesis algorithms and 5 sampler algorithms, each built for advanced sound design via simple controls. All eight drum channels can use both samples and synthesis simultaneously. 11 filter modes and 11 distortion algorithms add further sculpting options to each voice. Additionally, all eight drum channels contain rich modulation available for every parameter, including two LFOs, two envelopes, and more. A global Performance page shows a simplified interface that allows you to manipulate every drum channel simultaneously. Want to hear your drum beat tuned down an octave with a single knob? Done. Need a global boost to distortion or a dramatic filter gesture? Easy. Each drum channel contains two sequencers. The first sequencer is a manual step sequencer with ratcheting, probability, velocity, pitch, micro-timing, and more... per-step! Each parameter lane can run at a different speed and length, making generative, evolving patterns a breeze. The second sequencer combines Euclidean patterns with an Unfiltered-designed permutation engine. Both sequencers run in parallel and receive further shaping via an array of Sequence Modifiers. Want one drum sequence to speed up while another slows down? The SHAPE parameter is here for you. Need that hi-hat to be a bit lazy? SHIFT will nudge it to rush or drag. And if you think drum machines have no soul, wait until you combine per-channel SWING with global HUMANIZE. All of this advanced sound design is glued together with a flexible mixer and Unfiltered Audio's evocative effects. Battalion contains two new Unfiltered Audio effects: Shatter Delay and Headspace Reverb. Shatter Delay combines granular stretching, dynamic ducking, sample crushing, and feedback spectrum sculpting into a melange of echo bliss. Dubby, dark, dotted echoes? Chaotic glitch storms? It's all here. Headspace Reverb evolves Silo's ten classic reverb algorithms with additional filtering options. You will always find the perfect reverb for your drum mix. Battalion includes over 150 presets to get you started. These cover a wide variety of genres and tempos, from glitch and IDM by esteemed sound designer DataBroth, to futuristic hip-hop from Willie Green (head of our favorite Backwoodz Studioz). From smoky and loose to shiny and mechanical, Battalion is ready to be your go-to solution for every rhythmic task.
