Key Info

All the features of the Opsix MkII in a compact 4U 19" desktop/rackmount package.

MIDI 2.0 property exchange with polyphonic aftertouch

Stay at the forefront of technology with the Opsix Module's MIDI 2.0 Property Exchange and Polyphonic Aftertouch support. Thanks to the latest software updates, all models of the Opsix, both hardware and software, now offer MIDI 2.0 compatibility. This enables seamless communication between your Opsix MKII Module and other MIDI 2.0 devices.

Furthermore, the module boasts Polyphonic Aftertouch modulation, allowing for expressive and nuanced control over your sound. Whether you prefer using Channel Aftertouch or Polyphonic Aftertouch, the Opsix Module has got you covered.

Versatile rackmount/desktop design

Unleash your creativity with the Opsix MKII Module's versatile design, perfectly suited for both rack-mount and desktop setups. In a rack configuration, the module's panel is intelligently crafted to fit into a standard 19" width, ensuring seamless integration with your existing gear. The rear jack panel is recessed, providing easy access to cables even when mounted directly above.

With desktop setups, the Opsix MKII Module offers adjustable panel angles, allowing you to find the ideal position for your performance or studio work. Choose between a flatter angle for standing up and a more upright angle for comfortably seated operation.
