What makes it different

Most arps only give you a pattern. Arponaut lets you shape both the Pattern lane and the Chords lane.

Edit the Pattern lane and the Chords lane. Shape both sides of the arp instead of locking into a single pattern.

Send DAW MIDI into the Pattern lane, the Chords lane, or both. Mix played material with edited parts inside the plugin.

Because chords are editable too, routing MIDI into the Pattern lane opens combinations that standard arpeggiators can’t do.

Play, tweak, and experiment until it surprises you. Find fresh melodies and rhythmic ideas in seconds.

Update walkthrough, demo, and tutorials. Start with whichever fits how you learn.
