Autony vs BounceBud Physics Based MIDI
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
BounceBud Physics Based MIDI
This app generates MIDI notes through a unique physics-based system. Balls collide with customizable keyboards, triggering MIDI events. It offers extensive control over note scales, velocity, and MIDI channels for diverse musical creations.
- Physics-based generative MIDI sequencing
- Customizable keyboards with MIDI note triggers
- Adjustable ball count, speed, and size
- Configurable key/scale, velocity, and octave ranges
- Individual MIDI output per keyboard
- MIDI input for 'shoot walls' interaction
- Toggleable ball collision behavior

BounceBud is a physics based, generative MIDI sequncer. Each side of the app has a customizable keyboard that send a MIDI note when a ball collide with its key. You can specify the ball count, speed and size on the main screen with the knob controls. In the settings menu, you can set the key/scale, velocity range, octave. range and MIDI channel settings of the keyboards. You can also specify the notes individually per keyboard. All keyboards share the same key/scale that could also be changed with BrainBud. Each keyboard has its own MIDI output, so you can play different audio apps with BounceBud at once. Or you can disable the keyboard sides you don't want to use. With a MIDI input (from a MIDI keyboard or a MIDI sequencer app) you can 'shoot walls' from the keyboards. Balls can interact with the walls and it introduce more randomness to your generative sequence. You can control each keyboard by assigning them different MIDI input channels in the settings menu. You can also toggle the ball collision behavior in the settings menu. Whether balls can collide with each other or not, it creates different, interesting sequences every time. The size variety and ball variety can be change in the ball settings section in the settings menu. It adds randomisation to the size and speed values. You can change the ball color theme in the settings menu as well! BounceBud is a MIDI app and it does not produce any sound on its own. You need to route BounceBud's MIDI outs to your audio app's MIDI input. The AUv3 plugin app needs and AUv3 host app such as AUM, Loopy Pro, Logic Pro, Cubasis, Nanostudio, apeMatrix etc.

Verdict
The clearest difference is review sentiment: BounceBud Physics Based MIDI at 100% against Autony's 61%. BounceBud Physics Based MIDI also leads on rating (5.0 vs 4.5) and iOS requirement (13.0 vs 15.6). Autony's advantage is update cadence (every 5 days vs every 3 weeks) and price ($3.99 vs $5.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
