"StepPolyArp" is a real-time polyphonic and polyrhythmic MIDI step arpeggiator and step sequencer that offers versatile musical functionalities. This application, available as a standalone program or an AUv3 MIDI effect plug-in, seamlessly transitions between step arpeggiator and step sequencer modes, providing users with dynamic options for musical expression.

The software allows for the creation of intricate melodic structures either through automatic generation from played notes or chords or by independent playback without MIDI input.
