## What is Cycle?

Cycle is a time lag accumulator - a musical system that repeats the notes you play over and over until they gradually fade into silence. It's a simple but very powerful idea, allowing you easily create fascinating and often unexpected sonic textures. 

Cycle can be a delightful meditative experience. The system naturally lends itself well to long and slowly evolving musical ideas, which encourages you to slow down and listen carefully as notes gradually fade in and out.

Cycle can also be a great starting point for creating ambient music. Cycle features easy recording and exporting to both wav and midi files, as well as Inter-App Audio (IAA) and Audiobus support. Easily Airdrop or email recordings to your computer, and use them right away in your favorite DAW.

Features:

- 12 sound options. Samples by @electronisounds.
- 3 octave MIDI keyboard
- Inter-App Audio (IAA) and Audiobus support
- Controllable tempo
- Controllable reverb wet/dry mix
- Built-in metronome
- 5 colors

### 5/5 — Endless fun

*2025-05-23*

Interesting fade effect looping

### 4/5 — Cool exploration tool

*2024-09-24*

It’s a nice implementation of a Terry Reilly concept. Fun to play. My only wishlist item would be actual numbers on the tempo setting/tap tempo.

### 5/5 — Genial

*2023-09-30*

Sehr intuitiv und übersichtlich; ideal um es beispielsweise an ein modulares Synthesizer System anzuschließen und weiter zu bearbeiten 🕺🕺

### 5/5 — Export to wav and midi + free !

### 3/5 — Nice, but… Ableton link ? Bpm ?

*2023-06-10*

It’s beautiful, it sounds nice, but the tempo doesn’t allow to set precise BPM, which is weird. Adding ableton link would change the game. As it is, it’s impossible to use with any synchronized workflow.

### 5/5 — This is the most amazing app that has ever existed.

*2022-12-11*

After downloading and using this app I have now gained super powers that allow me to speak to inanimate objects. I am now taller than I was before. All thanks to this app.
