cykle is an inventive, semi-generative melodic step sequencer for iOS, iPadOS and Mac (Catalyst). cykle abstracts every musical parameter into its own sequence using decoupled sequencer lanes, producing complex and musically engaging patterns from the interactions between simple elements.

nb: cykle does not make sound by itself, you will need to connect it to a MIDI-compatible synthesizer app on your device, load it in an AUv3-compatible host (such as Logic Pro, Audiobus or AUM), or connect it to an external synthesizer, computer or any other MIDI-compatible sound generating device.

- universal app (works on both iPhone and iPad)
- works in both portrait and landscape mode
- works as an Audio Unit (AUv3) MIDI plugin or as a standalone (CoreMIDI) app
- sample-accurate sequencing engine
- slick and responsive native UI
- pattern snapshots selectable via MIDI input
- song mode / pattern chaining
- pitch playable by MIDI note input (arp and chord modes)
- configurable tempo, scale and key
- every channel can be routed to a separate MIDI destination and channel
- every channel sends MIDI note- and pitch-bend data as well as an arbitrary number of MIDI continuous control (CC) messages
- full AUv3 state- and preset-saving
- randomization features
- save and load patterns
- decoupled sequencer lanes for the following parameters:
- pulse
- pitch
- rest
- step length
- chance
- velocity
- accent
- gate length
- chance
- ratchet (note repeat)
- accidental (flatten/sharpen)
- transpose
- chord inversion
- octave
- harmonize
- pitch bend
- mappable MIDI CC values (e.g., filter cutoff, resonance, envelope, etc.)
sequences can be instantly transformed by the following actions:
- shift left/right/up/down
- rotate
- randomize
- mutate
- mirror
- reverse
- double
- bisect
- configurable clock division rate per sequencer lane
- configurable playback mode per sequencer lane (forward, backward, random, jump)
- MIDI clock output
- Ableton Link support
- works without internet connection
- no push notifications
- no ads or in-app purchases
- no third-party behavioural tracking tools
- ongoing development and support

Mighty oaks from tiny acorns grow

This has become my go to sequencer for operating inside AUM, because the genius idea of separating pitch, gate, pattern length etcetera from each other means that you can create surprisingly complex, musical, evolving sequences or polyrhythmic patterns from tiny seeds of a handful of notes.

The inclusion of scales means even musical klutzes like me can achieve pleasing results, and the dev has worked hard adding extra ‘lanes’ and capability to the app since it’s release.

It really is fantastic, and unlike some other sequencer apps, easy to get your head round, way easy to use, but great at creating something other than motorik rigid patterns.

The only thing that would make this perfect would be a programmable ‘song’ or clip player mode that would let you cue up a whole series of the existing ‘snapshots’ to play in sequence, randomly, or in other ways, in the style of some of the Bram Bos sequencers. Here’s hoping, but in the meantime: excellent! :)

One of the best Berlin School sequencers

This is one of the best sequencers for Berlin School. Great for evolving patterns and semi generative sequences.
Having said that, I would like to request two fixes/features:
- rewinding the transport in AUM does not reset all sequencer lanes in all presets. I would expect all of them rewound to step 1, but I notice that sequences often still start where they stopped.
- please provide an option to disable cykle fitting each note received via MIDI input into one octave. This would make the plugin a great MIDI effect.

Really good...

I really like this app. It’s very simple to use but very capable of complex and interesting results. I really wish I could have lengths greater than 1, that would make it my go-to jam sequencer.
