midiLFOs vs Autony
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
midiLFOs
This app generates MIDI modulation data using four independent LFOs. It can control parameters in other music apps or external synthesizers, offering various waveform shapes and modulation possibilities.
- Four independent LFOs
- 7-bit MIDI CC message generation
- Multiple standard LFO shapes
- LFO rate and amplitude modulation
- AUv3 MIDI effect support
- MIDI clock and Ableton Link sync
- MIDI input mapping

midiLFOs is a MIDI controller app and AUv3 MIDI effect that sends MIDI modulation control data to other music apps and external synthesizers. It has four independent LFOs that send 7 bit MIDI CC messages in repeating Low Frequency Oscillating patterns. The LFOs can be the various standard shapes (sine, saw, triangle, square, sample and hold) but can also modulate each others amplitude and rate to create even more interesting shapes. midiLFOs does not make music or sound by itself, it controls other MIDI capable synth apps and devices in your studio. You can use it to modulate the filter cutoff frequency of your favorite synth app, the pan position of the hi hats in a drum machine app, the feedback amount of a delay effect, or the pitch of an external hardware synthesizer. Or you can do all four at the same time. midiLFOs features: - Four independent LFOs that send 7-bit MIDI CCs - Easily configure CoreMIDI port, channel, CC# per LFO - Use in other apps as a MIDI Audio Unit Effect - Easily adjust shape, rate, offset, lag per LFO - Modulate the rate and amount of an LFO using other LFOs - Sync LFOs to MIDI clock or Ableton Link - Map trigger, LFO rate, and modulation amount values to incoming MIDI Designed to be easy to configure and use, midiLFOs gives you a quick to configure and easy to use MIDI LFO controller toy with extra features that also make it a useful pro music studio tool. AUv3 support requires an AU host app that supports MIDI effects, such as AudioBus 3, AUM, etc.
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

Verdict
The clearest difference is update cadence: Autony at every 5 days against midiLFOs's every 3 months. Autony also leads on price ($3.99 vs $4.99). midiLFOs's advantage is rating (4.9 vs 4.5) and review sentiment (79% vs 61%). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
