• 16-mode arpeggiator + Chord & Scale modes: Instant musical inspiration with built-in arps, chord voicings, and key/scale locking for harmonic play.
• Generative tools (Mutate, Spice & Dice): Create live pattern variations and inject controlled randomness into your sequences or arpeggiations.
• Universal connectivity: Four CV/Gate outputs, full-size MIDI DIN In/Out, Sync In/Out, USB-C interface and sustain/expression pedal inputs make it a central hub.
• OLED display + clickable encoder & RGB feedback: All editing on the hardware now, no external software required to tweak sequencer and arpeggiator settings.
