OXI Instruments One MKII – 8-Track Multitouch Sequencer with CV, MIDI & Bluetooth

The OXI Instruments One MKII is a standalone hardware sequencer that puts eight independent tracks, six sequencing modes, and deep modulation capabilities into a portable aluminium unit with a colorful multitouch grid and OLED display. With 8 CV outputs, 8 gate outputs, Bluetooth MIDI, USB host, and an 8-hour battery, it's the creative brain for modular systems, hardware synths, and live performance rigs — explore it at Soundium.

Key Features

• 8 Tracks / 64 Tracks: Eight independent sequencer tracks expandable to 64 — each with its own length, speed, start/end points, and MIDI routing
• 6 Sequencing Modes: Multitrack, Chord, Poly (7-voice), Mono, Stochastic (generative), and Matriceal (parameter decoupling)
• Chord Mode: 150+ chord variations with arpeggiator, harmonizer, and dynamic chord modulation
• 64 Modulation Lanes: Draw automation curves, record encoder movements, or route modulation to internal and external parameters
• Multitouch Grid: Colorful, responsive pad grid for melody creation, live performance, and intuitive editing
• 8 CV + 8 Gate Outputs: Direct Eurorack integration without external modules
• Bluetooth 5.0 MIDI: Wireless connection to synths, iPads, and computers
• USB Host: Connect MIDI controllers and keyboards directly without a computer
• SD Card Storage: Infinite project storage with seamless memory expansion
• 8-Hour Battery: Full day of standalone operation
• OLED Display: 1.53" bright screen with full parameter overview — no menu diving

Customer Benefits

The One MKII eliminates the laptop from your creative workflow. Its six sequencing modes cover everything from simple step patterns to generative compositions and complex chord progressions — all from hands-on hardware. The 8 CV/gate outputs mean direct modular control without translation, while Bluetooth and USB host let it drive your entire hardware setup wirelessly.
