A classic arpeggiator turns your chord playing into fast-paced melody lines, usually going up & down the chord notes. Dual arpeggio can do that, and a whole lot more. Twice. It has two independent arpeggiators, each with separate play modes, settings to length and velocity steps. But perhaps the coolest part is the pattern section that turns your chords into rapid-fire polyphonic patterns in ways that other arpeggiators don’t.
