Features
37-Note Slimkey Keyboard with Velocity & Aftertouch
Play melodies, layered chords, and expressive sequences on the 37-note Slimkey keyboard. Each key captures velocity and aftertouch, allowing nuanced performances for studio composition, live setups, or modular control. The tactile keybed responds to every input for precise musical expression.
Polyphonic Step Sequencer & 16-Mode Arpeggiator
Record, program, and chain up to 64 steps with 8-note polyphony. Use the built-in 16-mode arpeggiator, including Poly, Walk, Pattern, and Random, to generate melodic or rhythmic variations. Sequences can be edited live with overdub, mutate, and automation features for flexible, evolving patterns.
Mode-Aware Encoders with OLED Display
Four mode-aware encoders, plus a Control button, provide instant access to the Sequencer, Arpeggiator, Chord, and Mutate functions. The OLED display and RGB feedback clearly indicate parameter adjustments, helping you navigate sequences, arpeggios, and harmonic edits efficiently during live performance or studio work.
CV/Gate, MIDI DIN, USB-C & Sync Integration
Connect modular synths, vintage instruments, or DAWs through four assignable CV/Gate outputs, full-size MIDI DIN, and USB-C. Additional 3.5 mm Sync In/Out and TRS sustain/expression inputs allow flexible routing, timing, and real-time control across hardware setups, making it a central hub for hybrid workflows.
Chord & Scale Modes with Mutate, Spice, Dice Tools
Lock sequences to a key or trigger full chords using scale and chord modes. Use Mutate, Spice, and Dice tools to create controlled variations, randomized patterns, and evolving textures. Combined with touch strips, encoders, and arpeggiator functions, these features provide hands-on performance control over melodies, sequences, and rhythms.
