BandDelay vs PolyBud Polyrhythmic Sequencer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BandDelay
This app offers a unique approach to sound design by splitting audio into 27 bands, applying individual delay effects to each. It allows for real-time manipulation of delay times, levels, and feedback, enabling complex rhythmic and sonic variations.
- 27 band realtime multiband delay
- Frequency dependent level, delay time, and feedback
- Tempo syncable delay times
- Meta parameter for rhythm variations
- AudioUnit for hosts like Garageband
- Ableton Link compatible

The multi-band delay BandDelay is an exciting tool for sound design and loop manipulation in realtime. In contrast to common delay processors BandDelay splits the frequency spectrum of the input signal into 27 bands and applies a separate delay unit to each band. The delay times can be synchronised to the host tempo generating nearly infinite rhythmical and sonic variations of the input signal. For each of the delay bands you can specify the delay time, the level and the feedback amount separately. These parameter changes can even be automised in realtime for glitch free rhythmical morphings. A few high level parameters let you change the delay times and feedbacks of all delays with the turn of a single knob. - 27 band realtime multiband delay. - Frequency dependent level, delay time and feedback - Linear phase precision filters for maximal transparency - Tempo syncable delay times up to 6 seconds. - Meta parameter for quick access to rhythm variations - Effect AudioUnit for use in hosts like Garageband, Cubasis, AUM and others - Full AU parameter automation - Ableton Link compatible - stand alone / Audiobus 3 / IAA

PolyBud is a multitrack polyrhythmic AUv3 MIDI sequencer. You can add multiple note or MIDI CC tracks to the each pattern. The note tracks has the note, velocity, gate, ratchet, probability and randomisation modes. You can set different step lengths to the each mode which would introduce polyrhythmic variations immediately. Another great feature is the each track can run in a different rate which is great for creating unique polyrhythmic sequences. Also, you can assign different MIDI channels to the each track so that you can control multiple synths within a single PolyBud pattern. The MIDI CC tracks is great for modulating the synth parameters. You can introduce polyrhythmic modulations by setting the different step lengths and different rates to your MIDI CC tracks. Also, you can set a ramp value for smoothing up the CC value changes per step. If you set the ramp value to 0% then you can have the classic sample and hold modulation. PolyBud is a MIDI app and it don't produce any sound of its own. You need to route PolyBud's MIDI out to your audio apps in order to run PolyBud. For the AUv3 plugin, you need an AUv3 host app such as AUM, Cubase, NanoStudio, ZenBeats, BeatMaker, apeMatrix etc.

Verdict
The clearest difference is rating: PolyBud Polyrhythmic Sequencer at 4.9 against BandDelay's 4.4. PolyBud Polyrhythmic Sequencer also leads on update cadence (every 5 weeks vs every 8 months). BandDelay's advantage is chart position (#199 vs unranked). On price, review sentiment, ratings volume and ads there is nothing between them.
