Korg opsix mk II

The opsix mk II is an enthusiast-tier digital synth that puts hands-on 6-operator Altered FM synthesis behind physical sliders, with 64-voice polyphony for deep, fast sound design. Its 37 keys make it a strong creative tool for producers chasing complex digital timbres, but analog-warmth purists and anyone who needs full-size keys should look elsewhere.
