Autony vs PolyBud Polyrhythmic Sequencer
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Autony
This app generates evolving musical sequences using a MIDI signal. It can be constrained to scales and chords, transposed, and mutated for dynamic musical output. All controls are MIDI-automatable and it requires a host app to function.
- Generates evolving musical sequences
- MIDI output for synths and hardware
- Constrain sequences to scales and chords
- On-the-fly transposition
- Sequence mutation for dynamic evolution
- MIDI automation of all controls

AUv3 Midi sequence generator which generates musical evolving sequences that you can further automate or modulate via midi. A clever algorithm creates a musical sequence which is output as a midi signal which can be used to drive a software synthesiser or a hardware device. Various settings allow the sequence to be constrained to scales and chords, transposed on the fly and also allowed to gently mutate giving an evolving sequence. All the controls can be modulated or automated via midi. Needs a AU host like AUM and generates no sound on its own. "My solution has been to make the equipment unreliable in various ways." - Brian Eno

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.
