The new model has 37 velocity-sensitive slim keys with aftertouch, plus Pitch and Modulation touch strips for real-time control. Chord and scale modes join a polyphonic sequencer with up to 64 steps and eight voices, a 16-mode arpeggiator, pattern chains and creative Mutate, Spice and Dice tools. Users can make an arpeggiator riff, turn it into a sequence, transform it and apply Mutate for quick variations with live editing. Analog Lab Intro and Ableton Live Lite are included.

Four encoders directly access arpeggiator, sequencer and Mutate parameters, reducing menu use. They can also control custom MIDI CC and CV/Gate assignments. Other features include an OLED display with push encoder and RGB indication, a MIDI CC button with four banks for 16 assignable CCs in every mode, and four CV/Gate outputs: Pitch, Gate, Mod 1 and Mod 2, assignable to velocity, aftertouch, modulation wheel and other parameters. Connections include DIN MIDI I/O, 3.5 mm Sync I/O, a TRS sustain/expression pedal input and bus-powered USB-C MIDI. A power switch, Kensington lock slot and iPad support through a Camera Connection Kit are included.
