Altered FM Synthesizer
Korg - Opsix Module

Korg opsix Module Altered FM Synthesizer

4 RU Desktop/Rackmount Synthesizer All the features of the Opsix MkII in a compact 4U 19" desktop/rackmount package. A digital synth like no other, the Opsix Operator Mixer simplified FM synthesis for the first time, making it not just comprehensible but also controllable. With the addition of extra synthesis capabilities and programming, it offers a more efficient workflow and an even richer sound.

Opsix Mk II is a digital synth like no other. The Opsix Operator Mixer simplified FM synthesis for the first time, making it not just comprehensible but also controllable. With the addition of extra synthesis capabilities and programming, it offered a more efficient workflow and an even richer sound.

Now, Korg has created a new form of Opsix: the Module. This model supports MIDI 2.0 property exchange and poly aftertouch, andis an excellent companion to Keystage. It’s also fully compatible with the sounds of the original Opsix, Opsix mkII, Opsix SE, and Opsix Native software, as well as numerous excellent third-party libraries, keeping the updated sounds and software fresh. The new 19" rack-mountable enclosure has the same controls as the keyed models, yet is easily transportable and fits neatly into any studio or desktop production system.

at a glance • 4 RU Desktop/Rackmount Synthesizer
• True Six-Operator FM Synthesis
• Expanded 64 Voice Architecture
• Easy Colour-Coded Operators with 6 Modes
• 40 Preset and User Algorithms
• 3 EGs, 3 LFOs, 12 Virtual Patches
• 16-Step Polyphonic Sequencer

Illuminate Your Sound

'Operator Mixer'At the heart of every sound is the Operator Mixer – a set of six faders and knobs that invite exploration. Each of the 6 parts will light up to indicate whether it’s generating a sound, or modulating the sound; red indicates a carrier, blue indicates a modulator.. Changing the position of these controllers unlocks new sound-shaping possibilities to breathe fresh life into your musical ideas. This simple, powerful hands-on workflow is part of what makes Opsix unique, just like the creative possibilities it offers.

SubtractiveThe most widely used type of synthesis, related to removing parts of a waveform to get the sound you want. Opsix uses up to six envelopes and multi-modelled filters to achieve a broad array of classic and innovative tones.

Semi-modular Rerouting signal paths to change the sound, a spin through the algorithms section can dramatically reshape the base sound while changing how the six mixer parts work together. No patch cables required!

Analogue modellingAnalogue-style controls and plenty of stackable waveforms take you from digital to analogue-sounding in no time. Enjoy deep basses, crisp leads, thick pad sounds, fuzzy brass tones and so much more.

WaveshapingBy adding intentional distortion to the waveforms to achieve aggressive overtones, Opsix makes it possible to achieve gritty sounds overflowing with character.

Additive With six operators, the complete FM experience is possible with Opsix. Stacking waveforms and blending their harmonics is key to an expansive range of harmonious, dissonant, and tension-driven sounds. Head back in time and experience classic sounds heard throughout recording history.

Classic FMOpsix’s flexible and powerful architecture starts with true six operator FM synthesis. It easily delivers signature sounds heard on thousands of hits from the ‘80s through to today. Opsix also benefits from far more polyphony than other standalone FM synths available today.

Powerful Effects Processing

'Elevate your sound to the next level'Opsix has thirty high-definition effects that can be layered. Elevate your sound to the next level with options like chorus, phaser, delay and compressor, alongside world-class shimmering reverbs.

Polyphonic motion sequencingOpsix features an incredible step sequencer. Create your own sequences, or simply press the play button for each sound to experience the depth of sequence possibilities. Six notes per step can be recorded, with control over each note’s velocity, gate time, and playback timing.

Create long phrases or even make subtle shifts in timing to emulate strums or drum rolls – often not possible on typical 16-step sequencers! The motion sequencer in Opsix also lets you record changes of up to six parameters, creating smooth motion within a phrase, or building rhythms that change dramatically with each step.

Intuitive modulation matrixWith six operator modes and 40 preset algorithms, plus the ability to create your own, the modulation possibilities available within Opsix are mind-blowing.

The synthesis is supercharged with processors at the end of the signal chain. A MOD section works separately from the operators, with three EGs and three LFOs; and 12 virtual patches for a wide variety of routing possibilities. These features provide a vast range of modulation to both create swirling soundscapes and add rhythmic motion to your sounds.

Throw the dice with true randomisationUse the randomize feature if you’re in the mood for unexpected sonic discoveries. Press the dice button to completely scramble the synth’s parameters, generating a new, unique sound. You can choose to randomise all parameters, or just operators, algorithms or sequences.

You might strike gold with your roll, but if not, just try again or use the result as a starting point for your next new sound!

MIDI 2.0 Property Exchange and Polyphonic Aftertouch Support

Korg opsix Module Altered FM Synthesizer

full support for MIDI 2.0 Property ExchangeWith the latest software updates, all models of Opsix, hardware and software, now support MIDI 2.0 Property Exchange. Hundreds of the original factory sounds have been updated to include Polyphonic Aftertouch modulation (Channel Aftertouch is supported as well). All of this makes the Opsix Module an excellent companion to Korg's Keystage controller.

Rack-Mount and Desktop The Opsix Module is cleverly designed for both desktop and rack-mount use. The panel is redesigned to fit into a standard 19" width, and the rear jack panel is recessed to allow easy access to cables even with gear mounted directly above. With desktop setups, brackets offer a choice of panel angles: flatter for performing standing up, or more upright for working while seated in your studio.
