Otoo vs EP

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

EP-PatchStudio builds sample kits and multisamples for Teenage Engineering's EP-series hardware, then sends them to your device over USB. Now on iPhone and iPad. If you own an EP-133 K.O. II, EP-1320 or EP-40 Riddim, you know the squeeze: great sounds, a tiny screen and a slow road from a sample on your computer to a pad on your sampler. This app is the shortcut. Import audio, trim it, build a kit and load it onto the hardware. WHAT YOU CAN DO - Import WAV and AIFF from Files, iCloud Drive or straight from another app via the share sheet - Trim, fade and set the start and end of every sample by touch - Build full kits, lay out pads and tune each one (max 8 samples - EP device limitation) - Create multisamples for the EP-40 Riddim, mapped across the keyboard - Send finished kits to your device over USB MIDI - Export kits and backups to Files, AirDrop or your DAW WORKS WITH - EP-133 K.O. II - EP-1320 Medieval - EP-40 Riddim Multisamples are EP-40 Riddim only. No hardware to hand? You can still build and edit everything, then export it for later. Plug in over USB when you are ready to send. FREE AND PRO The Sample Editor is free. Building kits, trimming samples and exporting all work without paying anything. Pro unlocks sending kits straight to your device, as a one-off in-app purchase. Buy once, no subscription. Already bought EP-PatchStudio on Mac or Windows?

I built EP-PatchStudio because I wanted grown-up software for these little machines, and I keep improving it based on what the community asks for. If something is missing or broken, tell me.
