• 3-Band Multi-Effects Processor • Compact design with massive sonic versatility • Each band provides its own effect with mix blending control • Band effects: Saturator, LoFi, Ring Mod, Delay, Reverb, Chorus & Stereo Control • Frequency isolator equalizer (DJ style filter) • Two adjustable crossover points for low and high bands with a slope up to 48dB • Separate Dry/Wet output controls with an optional master Brickwall limiter • Multi-output support: each band can be routed to separate channels in your host • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Bandit is a multiband audio effect that splits your audio signal into three independent frequency bands, each processed with its own effect and then recombined to create the final sound. Choose from a set of effects, including saturation, lo-fi degradation, ring modulation, delay, reverb, chorus and stereo control, and blend them precisely within each band. Two adjustable crossover points give you full control over which frequencies are affected, allowing you to shape your tone with precision. By targeting each part of the spectrum separately, you can apply effects in ways that full-range processing simply cannot achieve. FAC Bandit is a powerful sound design tool for musicians who want to craft unique, personal, and exciting sounds, either subtly, without altering the original tone, or in a more creative way. This is an AUv3 Effect and requires a compatible host to work The in-app purchases are for tipping only, the app is fully functional without them Fac Bandit 2 is crafted from a trusted original. Check out the outstanding reviews from Version 1 below: • Great isolated multi band effects, use this one a lot -ChrizzBeatz • Excellent app! Very versatile and the per band FX is such a tasty concept -disbliss • Some apps do what they say they do. Some have a little extra that make you use them more than you thought. This one will constantly keep making you sound better. I thought I would use it for a little color here and there and I now use it at least twice in every track -EduardoG2 • Got all this guys apps and they are all excellent -69reasons • Fonctionnement et ergonomie au top -SoundofSound • One of the most amazing multi band effects you can buy for iOS music production. Fred’s apps are ways good quality and this one does not disappoint -Positiveforever The documentation is available at fredantoncorvest.com/FAC_Bandit.html
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.
- 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 clearest difference is in-app purchases: PolyPipe at none against FAC Bandit 2's 3. PolyPipe also leads on update cadence (every 2 weeks vs every 6 weeks) and iOS requirement (13 vs 16.4). FAC Bandit 2's advantage is rating (5.0 vs 4.6) and review sentiment (100% vs 75%). On ratings volume, ads, monetization model and device support there is nothing between them.
