Otoo is a streamlined, one-screen groovebox designed for frictionless music production. Built around an innovative free-form step sequencer, Otoo breaks away from rigid grids, allowing you to place, drag, and stack notes freely across independent rows. Whether you are sketching out ideas using the native built-in engine and sampler or hosting your favorite third-party AUv3 plugins, Otoo delivers a distraction-free environment that prioritizes speed and musical flow. On iPhone, the interface dynamically scales to give your AUv3 instruments a near-fullscreen home, paired with a compact, highly responsive keyboard for immediate creation on the go. Otoo also includes Otoo MIDI, an AUv3 MIDI processor version of the app. It brings Otoo’s pattern-based sequencing into compatible AUv3 hosts, where playback follows the host timeline and instruments are routed as MIDI Out destinations instead of audio instruments. Distraction-Free Workflow • The single-screen layout keeps your sequence, arrangement and mixer visible at all times so you never have to dive into menus. • A free-form step sequencer lets you place, drag, and stack notes across any row without rigid instrument or track restrictions. • Step editing mode gives you precise control over note length, velocity, and timing subdivisions. • The gesture-driven mixer allows for quick volume adjustments, muting, and soloing directly from the main grid. • 4 rows on iPhone and 5 on iPad, with multiple instruments available in each row at different steps • 2-octave keyboard for playing and learning real notes Sounds and plug-ins • Up to 8 instruments per project • Built-in sounds and sampler • Use any installed AUv3 instruments in a large, near-fullscreen view with a compact keyboard • Up to 2 AUv3 effects per instrument • Sampler with instant key-by-key recording and chromatic mapping Patterns to full songs • Build songs from simple patterns • Draggable loop markers for quick arrangement changes Performance mode • Live sequencer and audio effects such as reverse, beat repeat, randomize, swing, triplet, tape, and more • Play the pattern like a keyboard by tapping steps directly Other features • Main output with built-in level protection • Automatic metronome when recording live into empty patterns • Export patterns or full songs as WAV or MP3 for easy sharing • Export performances as perfect loops • MIDI export • Supported time signatures: 4/4, 3/4, 4/4T and sequencer swing.

CACHE is a fast and simple sample browser for iPhone, iPad, and AUv3 hosts. It lets you open your own sample folders, browse collections instantly, preview audio files, detect sample key, and drag sounds straight into compatible apps and hosts. Built for producers who work across iOS and iPadOS, CACHE solves a problem that has been strangely overlooked for years: some DAWs and AUv3 hosts still don’t include a proper sample browser. Until now, that often meant digging through Files, switching between apps, and dragging samples in from outside your music workflow. CACHE puts that missing browser exactly where you need it. Use CACHE to: Browse your own sample folders and subfolders Preview one-shots and loops quickly Detect likely sample key for one-shots Drag samples directly into compatible DAWs, hosts, and apps Access collections from local storage, cloud locations, or external drives CACHE does not include any samples and does not make sound on its own beyond sample preview. You must supply your own sample folders. CACHE also does not copy or store your samples internally. It simply bookmarks and browses the folders you choose, so it won’t take up extra storage space with duplicate sample libraries. That makes it especially useful if your sounds live on external storage or outside the app itself.
