TATAT is a MIDI FX designed to create always-changing sequences, to quickly sketch music ideas, to add unexpected events to fixed patterns. If you’re looking for new ways of generating musical ideas, then look no further than TATAT! Set up your parameters, define a mood and listen to an endless flow of notes which you can then record, tweak, and play along to. HOW IT WORKS /// TATAT generates infinite and always changing sequences of notes. You cannot say exactly what TATAT will do, but you can suggest a path to it: by setting up its parameters you can create what we call a mood for TATAT. A mood is a configuration of notes, intervals, time fragmentation, velocity fluctuation, and other factors. Once you set a mood that you are happy with, you’ll listen to an infinite stream of events, always changing, all staying in the mood. 
At this point, according to your needs, you can: - Let TATAT play its stream, and make some intervention to control it: to add silence (Less), to obtain smooth accelerando and ritardando (Ratio), to control how TATAT generates intervals. You can enable Key In function to change notes on the fly. - Add some stability by controlling/automating the Liv/Mem slider, moving between the generated stream and frozen patterns. - Use TATAT to send its notes to enrich (by enabling Thru) existing/incoming MIDI data/parts. TATAT gives you excellent results both with melodic/harmonic and percussive parts! MULTIPLE TIME RES /// Set chance for each time resolution to rule the stream, and scale results with main ratio to create organic time fluctuations. NOTES /// Set chance for each notes to get triggered, enable the keys toggle to change the notes on the fly, giving a different color to the stream. DOUBLE HIT /// Set two intervals and the probability they got triggered, adding harmonic weight to the stream. LET’S PROCESS THE STREAM! /// You can process the generated notes with several parameters: add a velocity variation, a delay, set the length, randomize, and mute some notes. It’s easy and intuitive. FLOW VS PATTERN /// LIV/MEM parameter has a 0-100% range. When is set on 0%, a buffer with given length continuously records the stream; when it’s different than 0%, the buffer got locked, and you set the chance to get live or buffered notes. When you set 100% you always have the buffer content as a static pattern. You add the stability you want to the lunatic stream! 2 FLAVOURS: DARK AND LIGHT SKIN *** Please note: TATAT is an Audio Unit extension (AUv3) – it only works in an AUv3 host app compatible with MIDI FX like AUM, Logic Pro, Cubasis, etc... ***

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.
