Korg's fresh and expansive reimagining of classic digital synthesis, the Opsix Altered FM synthesizer delivers wide versatility and a full-spectrum, high-definition sound in an easy-to-use synth. From bells and chimes to sharp leads and wooly basslines, the Opsix handles it all in strides thanks to a unique "altered" FM synthesis approach. By sidestepping the often frustrating drawbacks of complex traditional 6-operator FM (Frequency Modulation) sound generation in favor of a much more musical and immediate approach, the Opsix houses a staggering amount of power, wrapped in a tidy, 37-key chassis with accessible hands-on controls that give you the real-time sound-shaping you would sooner expect to find on an analog synth. The core of this synth's expansive voice is its Operator Mixer, a series of six illuminated knobs and faders attached to different parameters for tonal tweaking as you see fit. Boot it up, and you're instantly met with hundreds of presets to lay a solid base to explore.
