Description

"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.

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 doesn't 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, Audiobus MIDI sender, MIDI filter routing, Ableton Link sync, and MIDI clock source sync. An internal sound bank is included.

The Audio Unit 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 MIDI effect format.

Amazing

Extremely well made, well thought out app for arpeggios and sequences. This thing handles the bread and butter while opening up possibilities I hadn't even thought of.

Also, I had a support question and the response from the developer was really quick. You get what you pay for folks, and this one's well worth it.

Amazing

I love sound design and mixing, but I am not a musician. By using midi song kits I have been able to find new arrangements to mix, but it can be an expensive endeavor. This app, along with Odesi (for chords, bass, and drum midi), let’s me generate pitch perfect midi tracks in seconds, which I can then voice with the synth of my choice and mix to taste in Cubasis. Thank you to the dev! 🙏🏾

Great Arpeggiator!

Capable of doing just about anything you can think of. Integrates perfectly with Cubasis.

There’s a bit of a learning curve to climb, but the results are worth it. Make sure to read the manual. Tech support is very quick via email from the author of the software.
