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. features: - 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

"StepPolyArp" is a real-time polyphonic and polyrhythmic MIDI step arpeggiator and step sequencer. It can be used as a standalone application or as an AUv3 MIDI effect plug-in. The application and the plug-in can operate as a step arpeggiator, automatically generating melodic patterns from played notes or chords, or as a step sequencer that does not require MIDI input to play. Unlimited presets can be saved locally and synchronized with iCloud. Each preset contains 16 patterns, 5 customizable polyrhythmic step controllers, and a 32-step event matrix with 11 polyphonic and polyrhythmic lines driving the arpeggiator engine. The application supports full internal and external MIDI connections for input and output, Ableton Link synchronization, and MIDI clock synchronization. An internal sound bank is included. The AUv3 MIDI effect plug-in supports multiple instances. A compatible host is required to run the plug-in. The host must support the Audio Unit v3 (AUv3) MIDI effect format. Hosts supporting AUv3 MIDI effect on iOS: Logic Pro, Cubasis, Beatmaker, AUM, Audiobus, NanoStudio, Auria Pro, apeMatrix. Hosts supporting AUv3 MIDI effect on macOS: Logic Pro 10.7 or later.
