Autony vs ShiftBud Generative MIDI AUv3
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
ShiftBud Generative MIDI AUv3
This app generates random MIDI sequences using a shift register chip, inspired by a popular eurorack module. It offers extensive control over scales, octaves, velocity, and MIDI CC modulation, allowing for complex and evolving musical patterns.
- Random looping generative MIDI sequencing
- 16-bit shift register logic
- Adjustable chaos for sequence variation
- Over 110 scales plus custom scales
- MIDI CC generation and modulation
- Unlimited pattern pages
- Manual trigger function

ShiftBud is a random looping generative MIDI sequencer based on the eurorack module Turing Machine by Tom Whitwell. It works based on the 16-bit shift register chips where it shifts its value on each sequencer step. However, you can lock the sequence in a desired length if you fully rotate the chaos knob to the left or right. If you introduce low amount of chaos, then the sequence "flips" occasionally and generate beautiful sequences. You can also produce random values if set higher amount of chaos. The MIDI note generation can be in more than 110 scales plus your custom ScaleBud 2 scales. You can set the octave range, velocity or velocity randomness as well. You can set the higher and lower bounds on MIDI Control Change generation as well as the CC number you want to control. It's very useful on modulating synth parameters and you can even modulate the ShiftBud's AU parameters as well. You can also set a ramping value for a smoother change. With the 0% ramping, you can use it like a "sample and hold" module. With the manual trigger function, you can use another sequencer or keyboard to trigger ShiftBud's next note. You can create unlimited pattern pages on the lower left corner of the app and you can select the pattern with MIDI CC messages as well. Please note that ShiftBud is a MIDI app. The standalone version has an optional internal synth where you can enable or disable on the settings menu. The AUv3 plugin requires an audio app for output. For the AUv3 functionality, it needs to be hosted within an app such as AUM, Loopy Pro, Cubasis, Logic Pro, Nanostudio, Drambo, or apeMatrix.

Verdict
The clearest difference is update cadence: Autony at every 5 days against ShiftBud Generative MIDI AUv3's monthly. Autony also leads on price ($3.99 vs $5.99) and ratings volume (40 vs 9). ShiftBud Generative MIDI AUv3's advantage is rating (4.7 vs 4.5) and iOS requirement (13.0 vs 15.6). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
