The Korg Radias gives you a lot of control over Omnisphere in a fairly small space. It can take a little time to get used to navigating its layout, but you can control two Oscillators with FM, Ring Mod, Unison, and Waveshaper. It has a Dual-filter section with multiple Filter types, FX, Mod Matrix, as well as an arpeggiator and a sequencer that will send MIDI to Omnisphere. You can get it with the keyboard or as a standalone desktop/rack module. It’s discontinued and somewhat expensive on the used market, but in addition to being a good controller for Omnisphere, it’s a pretty powerful synth.

Korg Radias Strengths:

  • Powerful Layout
  • Step Sequencer
