About

PolyPipe

This app is a multi-lane polyphonic sequencer plugin for creating evolving musical patterns. It allows for independent control of rhythm, pitch, and modulation across multiple lanes, generating complex and unique sequences in real-time. Ideal for generative music and experimental pattern creation.

Highlights
  • Multi-lane sequencer with 4 independent lanes
  • Pattern-based structure with multiple patterns per lane
  • Advanced step parameters (pitch, velocity, gate, probability)
  • Chord-aware steps and chord strumming
  • Multiple step modes (random, chord, bass, hybrid)
  • Polyrhythmic playback with differing lane/pattern lengths
  • Probabilistic sequencing with per-step chance

PolyPipe is a multi-lane, polyphonic AUv3 sequencer plugin designed for creating evolving musical patterns rather than fixed, repetitive loops. Instead of thinking in terms of a single step sequence, PolyPipe lets you build multiple independent lanes, each with its own rhythm, pitch logic, octave behavior, probability, and modulation data — all running together as a coherent musical system. It comprises elements of some of my favourite sequencers of all time, all rolled into a single interface. At its core, PolyPipe takes incoming MIDI notes (or internally generated notes) and uses them as a musical “seed.” These notes are then processed through patterns, scales, transposition rules, and step logic to generate new musical phrases in real time. This makes it especially suited for generative music, complex arpeggiation, bass-and-chord splitting, and long-form evolving sequences. Each lane in PolyPipe is its own sequencer voice. A lane contains one or more patterns, and each pattern is made up of steps. Steps don’t just define when a note plays — they can also define how it plays. A step can include pitch offsets, velocity, gate length, strumming, probability, repeats (ratchets), ties for legato behavior, and even chord information. Patterns can be enabled or disabled independently, shifted by octaves, and combined with global transposition. Because lanes can have different lengths, directions, and step modes, the resulting sequences naturally phase against each other, creating variation without manual intervention. PolyPipe applies musical logic at the MIDI output stage rather than hard-coding notes upfront. Pitch values can be forced into a chosen scale and key, allowing even highly experimental patterns to stay musically coherent. Different step modes (such as forward, backward, ping-pong, random, chord, bass, or hybrid note/chord modes) let each lane behave differently, from traditional arpeggios to controlled chaos. PolyPipe Sequencer is built for musicians who want to explore ideas quickly, create unique patterns, and discover results they wouldn’t think to program manually. It rewards experimentation: small changes to probability, repeats, or step logic can dramatically alter the musical output while staying rhythmically locked and musically usable. PolyPipe Features ○ Multi-Lane Sequencer: with 4 independent lanes. ○ Pattern-Based Structure: where each lane contains multiple patterns. ○ Advanced Step Parameters: including pitch offset, velocity, gate length, auto-roll, repeats (ratchets), and legato ties. ○ Chord-Aware Steps: allowing steps to trigger chords, rotated voicing, or individual notes depending on lane mode. ○ Multiple Step Modes such as Up, Down, Ping-Pong, Random, Drunk, Chord, Bass, and hybrid note/chord modes. ○ Chord Strumming: allowing 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 for evolving patterns. ○ Octave Transposition Control: per pattern and globally for rapid harmonic variation. ○ MIDI CC Sequencing: allowing lanes to output modulation data. ○ Real-Time MIDI Interaction: where incoming notes influence pitch selection, chords, and playback behavior. ○ Live-Safe Parameter Editing: with immediate feedback and no need to stop playback. ○ Generative-Focused Design: optimized for long-form evolving sequences rather than static loops. ○ Long Patterns: up to 32 steps in length, chain-able up to 128 steps. ○ 4 MIDI Output Ports: allowing each of the 4 phase-locked arpeggiators to be routed to a different instrument. ○ Global Swing: allowing 8th- and 16th-note swing across all 4 arpeggiators. ○ Rhythm Generator: creates rhythmic patterns that are none chord/scale specific.

About

Augmatic GRE

Generate complex and evolving drum patterns using algorithmic and Euclidean engines. This app creates MIDI notes that require a separate sound source to produce audio, offering deep control over rhythm and dynamics.

Highlights
  • Algorithmic and Euclidean rhythm generation
  • Morphable Grids Engine for evolving beats
  • Blend control between pattern types
  • Linear drumming for articulate patterns
  • Velocity bender for expressive dynamics
  • Groove tools for swing and timing
Read full description

MAIN FEATURES: - 6 Algorithmic Channels - Bass drum, snare, hi-hat, plus accents which create complementary rhythms, not duplicates. Each channel can generate its own rhythmic voice for rich, layered drum patterns. - Topographic Engine - Morphable, evolving beats based on the Mutable Instruments Eurorack module. Navigate an X/Y map of interconnected drum patterns extracted from actual drum loops with smooth interpolation between patterns. - Euclidean Engine - generate evenly distributed, world‑inspired rhythm patterns using Euclidean algorithms. Configure steps, hits, and start position independently on each channel for precise control. - Blend Control - Crossfade between Grids and Euclidean patterns to introduce variation while preserving the core character of your groove. - Linear Drumming - Control which drums play together or play alone. Eeach sound has room to breathe. Creates clean, articulate patterns. Used in Hip-Hop, IDM, Funk, Fusion. - Velocity Bender - Shape velocity dynamics for a more expressive, dynamic pulse. Create ghost notes, and rhythmic emphasis that bring patterns to life. - Groove Tools - Swing, humanization, clock division, and timing shift. Fine-tune the feel of your patterns from tight and mechanical to loose and human. IMPORTANT: This app does not produce sound on its own. It generates MIDI notes and requires a drum sampler or synthesizer to play them.

Verdict

The call

The clearest difference is price: Augmatic GRE at $9.99 against PolyPipe's $14.99. Augmatic GRE also leads on rating (4.9 vs 4.6) and review sentiment (83% vs 75%). PolyPipe's advantage is iOS requirement (13 vs 15.0). On ratings volume, update cadence, ads and in-app purchases there is nothing between them.
