Korg opsix mk II, Altered FM synthesizer with 37 keys

The Korg opsix mkII is an FM synthesizer with 6 operators, based on Altered FM. In addition to classic FM, it offers five additional operator modes: Ring Mod, Filter, Filter FM, Wave Folder, and Effect. With 64 voices, it is also capable of producing expansive soundscapes and full FM pianos, with an optional sustain pedal. The operator mixer provides each operator with its own volume fader and tuning knob, while LED colors indicate which operator is acting as a modulator or carrier.

There are 40 algorithms, and you can also create your own algorithm for each patch. The multimode filter and three effect blocks further process the sound. The polyphonic step sequencer has 16 steps, and motion sequencing allows you to automate virtually all parameters. The modulation matrix features three envelopes, three LFOs, and 12 virtual patch connections. The randomize function lets you create new patches based on random chance.
