TETSUO vs ThreeTuring
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
TETSUO
This app offers a unique, generative percussion experience with no pre-loaded samples. It features a complex sound engine and a dynamic sequencer that can be unpredictable, allowing for negotiation rather than direct programming. Create and save evolving soundscapes with its section-based recording system.
- Chaotic percussion engine
- No samples or library
- Resonant filter and bitcrusher
- Dynamic 16-slot sequencer
- Randomized hit skipping
- Section-based sound recording
- AUv3 and standalone support

TETSUO is a chaotic percussion machine. No samples, no library. One voice built out of a pitched body with noise dragged through it, a resonant filter that saturates the harder you lean on it, a bitcrusher, and a waveshaper that runs from a bit of weight to total structural failure. The sequencer is sixteen unseen slots and STEPS knob decides how many of them fire, adding and taking away hits one at a time in a fixed order, so you can strip a pattern to the bone and build it back and the same beats come home. The SKIP control works against you on purpose, stealing hits at random while it plays, so it never quite settles. MUTATE modulates the pitch at random, setting fire to voices on every turn. You do not program TETSUO so much as negotiate with it. The strip along the top is how you attempt to hold onto anything. Sixty four steps, four turns of pattern, carved into as many as eight sections. Select a section. Find a sound. Hit RECORD, and that section keeps every knob position. Change it, record the next, then hit PLAY and it walks left to right dropping each snapshot in as it reaches it, looping. Drag the dividers to give a section longer or cut it short. It keeps settings, not audio, so the engine is playing live the entire way through. Sections save with your presets and your session. Fifteen factory presets to start from, and your own saved alongside them. A preset stores the knobs and the whole arrangement together. Tap the round gauge in the middle for presets, settings and the manual. AUv3 plugin and standalone app. Follows host tempo and transport, twelve automatable parameters, full MIDI control, factory and user presets, and a manual built into the app.
ThreeTuring
Create evolving musical sequences with a semi-modular groove box. This app offers a hands-on, hardware-like creative experience without complex menus. It features a dual oscillator monosynth, generative modules, and a modmatrix for extensive control.

Construct evolving sequences. The creative experience of using a constrained hardware system rather than the lazy freedom of just being able to “add another module”. ThreeTuring lays out everything in front of you without the need to keep going back to the manual. No menu diving, no alternative pages and easy to pick up if you haven’t used it for a few weeks or months. Having fun making music. ThreeTuring consists of a dual oscillator monosynth, a clock module for generating trigger patterns alongside a collection of generative modules encompassing a range of modular generative techniques including a turing machine, random generators, LFOs, envelope generators, a quantiser, a note accent and a set of effects modules. Pretty much every control can be modulated via the nine slot modmatrix, including the modulation settings themselves.
