It combines a synthesizer engine with recreations of named Roland instruments, modern RD pianos, and Roland drum machines, alongside more than 4,000 preset tones and over 90 drum kits. I-Arpeggio listens to notes, rhythms, and phrases, then generates complementary drums, bass, chords, and arpeggiated material that can be customized and sent to a DAW.
