StepPolyArp

StepPolyArp is a real-time polyphonic and polyrhythmic MIDI step arpeggiator and step sequencer.
It can be used as a standalone application or an AUv3 MIDI effect plug-in.

The application and the plug-in can operate as a step arpeggiator by automatically generating melodic patterns from played notes or chords, or as a step sequencer that doesnt require MIDI input to play.

Unlimited presets can be saved on a local device and synchronized to iCloud.
Each preset contains 16 patterns, 5 customizable polyrhythmic step controllers, and a 32 steps 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 sync, and MIDI clock source sync.
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 needs to support the Audio Unit v3 (AUv3) MIDI effect format.

Hosts supporting AUv3 MIDI effect: Cubasis, Beatmaker, AUM, Audiobus, NanoStudio, Auria Pro,apeMatrix.
