Product Description

Opsix Mk II is a digital synth like no other. The Opsix Operator Mixer simplified FM synthesis for the first time, making it not just comprehensible but also controllable. With the addition of extra synthesis capabilities and programming, it offered a more efficient workflow and an even richer sound.

Key Features:

  • Increased polyphony.
    Compared to the original, the number of available voices has been almost doubled in Comparison.
  • Amazing effects:
    Effects can make even some of the worst sounds sound good, so imagine what they could do on an instrument that already sounds good without them! The Opsix MKII has an entire arsenal of effects ready to go to make its already stella sound, even more out of this world.
  • Incredible real-time control:
    A large OLED display showcases important information on the fly, combined with a lot of hands on control, this gives amazing access to FM synthesis which is notoriously one of the harder synth styles to edit, but not anymore.
