StepPolyArp has been a very popular arpeggiator and step sequencer for iOS for a quite a few years now. Now the developer of StepPolyArp brings us a new App & Audio Unit MIDI effect for iPhone, iPad with iOS 11.0 or later. StepPolyArp Unit is a real-time polyphonic and polyrhythmic MIDI step arpeggiator and step sequencer. It can be used as a standalone application or an Audio Unit MIDI effect plug-in.
