Did you know this module doubles the polyphony of its acclaimed predecessor, jumping from 32 to 64 voices for lush, worry-free layering in your patches? It's the rackmount/desktop version of Korg's opsix mkII, perfect for integrating into any setup without taking up keyboard space.
At its core is the Altered FM engine with six operators, each switchable between FM, ring mod, filter, filter FM, wave folder, or effect modes, plus 40 preset algorithms and user-customizable ones for sounds from icy chimes to gritty basses. Hands-on controls include dedicated Ratio knobs and Level sliders for operators 1-6, six Data Entry knobs, mod and pitch wheels, plus a multimode filter modeling classics like the MS-20 and PolySix in lowpass, highpass, bandpass, and more. Three EGs, three LFOs, and a 12-slot virtual patch matrix fuel deep modulation, while the 16-step motion sequencer records up to six notes per step with velocity/gate tweaks and automates parameter changes. Thirty effects span chorus to shimmer reverb, with stereo outs, headphone jack, USB/MIDI DIN I/O, arpeggiator, and 500 programs (350 presets, 150 user).
Players love its intuitive operator mixer with glowing green pointers for quick tweaks and the "dice" button sparking fresh ideas, though some wish for front-panel filter controls and onboard multitimbrality. At 483 x 172 x 113 mm and just 1.7 kg, it's a lightweight powerhouse for studios or live rigs.
