Autony vs TfxEcho
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
TfxEcho
This audio plugin offers a warm, dark echo effect inspired by analog delay units. It allows for adjustable delay times, feedback, and filters, with modulation capabilities and tempo syncing. The plugin captures high-frequency signals for a versatile sound.
- Echo and delay effect
- BBD-inspired delay lines
- Adjustable delay time (20-1200 ms)
- Feedback control (0-100%)
- Low-pass and high-pass filters
- Modulation rate and width
- Tempo sync

TfxEcho is an echo effect AudioUnit Extension plugin. It uses delay lines which are inspired by BBD (bucket brigade device). BBD is used in various analog delay unit and is known for its warm and dark sound. The delay line uses fixed length buffer and an artificial clock to sample input signal in variable sampling rate. When the delay time is changed, the delay line can produce pitch change effect which is similar to the behavior of the BBD based analog delay unit. The delay line is inspired by BBD, but it is not emulation of the any particular BBD. Unlike the typical BBD based delay unit, frequency range of the delay line is not limited. The delay line is capable to capture signal in higher frequency up to about 22KHz. Features AudioUnit Extension - Delay Time: From 20 ms to 1200 ms - Feedback: From 0 % to 100 % - Adjustable lowpass filter and high-pass filter. - Modulation rate: From 0.01 Hz to 10 Hz - Modulation width: From 0 ms to +/- 10 ms - Delay time can be synced to tempo provided by the host application. Host Application Host application uses system audio input as an audio source and processed audio signal is routed to the system audio output.

Verdict
The clearest difference is update cadence: Autony at every 5 days against TfxEcho's every 3 months. Autony also leads on ratings volume (40 vs 12) and price ($3.99 vs $4.99). TfxEcho's advantage is review sentiment (80% vs 61%) and rating (4.7 vs 4.5). On ads, in-app purchases, monetization model and device support there is nothing between them.
