BLEASS Peaks turns filtering into a fully playable musical experience. Built around a powerful multi-peak bell-style filter engine, it lets you shape and animate sound in ways that go far beyond traditional effects. Create rich filter responses with up to 32 resonant peaks or notches, and sculpt their distribution, width, and behavior with intuitive controls. Everything is designed to be both immediate and deep, so you can quickly dial in a sound and push it into more experimental territory. Switch to MIDI mode and Peaks reveals its true potential. The filter becomes an instrument you can play, with frequency controlled directly from incoming notes. With up to eight simultaneous filter voices, you can turn rhythms into harmonies, add movement to static sounds, or create evolving textures that follow your performance. A comprehensive modulation system brings constant motion and life to your sound. 3 LFOs, envelopes, macros, and MIDI sources can be freely assigned to parameters, making it easy to build subtle movement or complex, reactive behaviors. BLEASS Peaks also includes a flexible effects section with five processing slots, allowing you to shape and enhance your sound further with distortion, dynamics, delay, and filtering. Every stage can be modulated, opening the door to deeply expressive and evolving effects. Despite its depth, Peaks remains fast, fluid, and intuitive to use. Its responsive interface, real-time visualization, and performance-ready controls make it equally at home in the studio or on stage. From precise tonal shaping to bold, animated transformations, BLEASS Peaks gives you a new way to hear and perform your sound. Optimized for iOS, it delivers high performance, low CPU usage, and a smooth, touch-friendly workflow built for modern music production. BLEASS Peaks Plugin is also available for Desktop.

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.

Verdict

The call

The clearest difference is rating: BLEASS Peaks at 5.0 against PolyPipe's 4.6. BLEASS Peaks also leads on review sentiment (100% vs 75%). PolyPipe's advantage is ratings volume (10 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

BLEASS Peaks costs $14.99 and PolyPipe $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

BLEASS Peaks holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: PolyPipe has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of BLEASS Peaks's written reviews are positive against 75% of PolyPipe's.
