The app lets you build multiple independent lanes, each with its own rhythm, pitch logic, octave behavior, probability, and modulation. Notes are treated as musical “seeds” that get processed through patterns, scales, transposition rules, and step logic in real time. This makes it perfect for generative music, complex arpeggiation, bass-and-chord splitting, and long-form evolving sequences. Early users on the Loopy Pro forum and X are already calling it “the sequencer that finally breaks the grid” because small changes in probability or step mode can dramatically transform the output while staying rhythmically locked and musically coherent.
What really stands out is how musical and performance-friendly it feels. You can draw notes freely or use the generative tools to spark ideas quickly, and every step can include pitch offsets, velocity, gate length, strumming, repeats (ratchets), ties for legato, and even chord information. Patterns can be enabled/disabled independently, shifted by octaves, and combined with global transposition. Because lanes can have different lengths and directions, the sequences naturally phase against each other, creating variation without any manual intervention. It runs as an AUv3 MIDI effect in hosts like AUM, GarageBand, Cubasis, or Drambo, and the clean, modern interface makes complex polyphonic sequencing surprisingly approachable on both iPhone and iPad.
For how to make music on iPad, PolyPipe rewards experimentation in a way few sequencers do. Route different lanes to separate instruments or effects and watch the music breathe in real time. It’s especially strong for live performance and sound design, where the probabilistic and generative elements keep things interesting over long takes. No MacOS version yet, but the low CPU footprint means you can run several instances without issues. If you’re into generative or performance-based MIDI, this feels like one of the most exciting new tools of 2026.
Key features include:
- 4 independent lanes with individual rhythm, pitch, octave, probability, and modulation
- Pattern-based structure with up to 32 steps per pattern (chainable to 128 steps)
- Advanced step parameters: pitch offset, velocity, gate length, auto-roll, repeats (ratchets), ties for legato, chord information
- Multiple step modes: Up, Down, Ping-Pong, Random, Drunk, Chord, Bass, and hybrid note/chord modes
- Chord-aware steps and guitar-like strumming patterns
- Polyrhythmic playback through lanes and patterns of differing lengths and directions
- Probabilistic sequencing with per-step chance and variable repeat behavior
- Octave transposition control per pattern and globally
- MIDI CC sequencing for modulation data
- Real-time MIDI interaction where incoming notes influence pitch selection and playback behavior
- Live-safe parameter editing with immediate feedback
- Generative-focused design optimized for long-form evolving sequences
