Critic Reviews

Korg OpSix SE & Wavestate SE

soundonsound.com

The Korg Opsix SE enhances the original's capabilities with a robust design and improved keybed, catering well to live performance needs. However, it retains shortcomings like the absence of expression pedal inputs and reliance on an external power supply. While the polyphony has increased significantly, the lack of substantial new features might disappoint those expecting a groundbreaking update. The SE model offers a more professional feel but raises questions about its value given the price hike. Overall, it’s a solid synthesizer, but whether it's worth the investment depends largely on your specific requirements as a musician.

Korg Opsix SE and Wavestate SE review | MusicRadar

musicradar.com

Korg's Opsix SE and Wavestate SE elevate FM synthesis and wave sequencing with solid builds and expanded features. However, the upgrades may not justify their high price tags for existing users of the original models. The small screens and limited added functionality leave some potential buyers wanting more, while the included hard case and improved key action do add value. Ultimately, these special editions shine but are best suited for those who truly need their specific enhancements rather than as essential upgrades.
