Notes: Second-gen version of the excellent Opsix features major updates including 64-voice polyphony and an improved interface. Same powerful six-operator FM synth engine.

Supplier's Notes:
A Full-Spectrum Sound Experience

Opsix mk II is a digital synth like no other. Based on the sound engine of the original Opsix, the number of simultaneous voices and voicings has been expanded to an astounding 64 voices. The result is superior performance and precise control.

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.

And, it is fully compatible with the sounds and samples from both the original opsix and the opsix Native software, including numerous high-quality libraries.

Evolved to an astounding 64 voices

The Opsix mk II has 64 voices, twice as many as the original 32 voices, allowing users to enjoy tone editing without having to worry about the number of simultaneous voices. In addition, the operator-mixer section, the most distinctive feature of this product, has been accented with a new image colour, green.

Get Illuminated with the Operator Mixer

At the heart of every sound is Opsix mk II's Operator Mixer - a simple set of six faders and knobs that invite exploration. Each part lights up red to indicate carriers or blue for modulators. Manipulating them opens up new sound-shaping possibilities to breathe fresh life into your musical ideas. This straightforward, hands-on workflow is part of what makes Opsix mk II so unique, just like the sounds it offers.

Direct Hands-On Control

Whether you're tweaking a preset or building a patch from the ground up, the six data entry knobs on the right give you quick access to the parameters you need and seamlessly sync with the large OLED display, giving you a clear, focused direction to your workflow. Coupled with the mixer, it makes creating fresh sounds super easy and, most importantly, fun!

Select from a full range of analogue-style filters, from the radical Korg MS-20 low-pass/high-pass filter to the powerful yet smooth KORG Polysix low-pass filter that gives your sound a vintage feel. There are also two or four-pole low-pass, high-pass, band-pass, and band-reject filters with resonance.

There's even a built-in spectrum analyser and oscilloscope that gives you visual feedback via the screen on the music you're making.

Six in One Synthesis

The core of Opsix mk II is nothing short of exponential. Since waveforms can be arranged and modulated in nearly infinite ways, Opsix mk II can easily do the sonic work that is similar to numerous types of synthesis:

Subtractive

Removing parts of the sound to get the sound you want; the most widely-used synthesis. Opsix mk II uses up to six envelopes and multi-modelled filters to achieve many cutting-edge and classical analogue synthesis tones.

Semi-Modular

Rerouting signal paths to change the sound. A spin through the Algorithm section will dramatically reshape the sound by changing how the signal routing between the operators work together, and no patch cables are needed. Analog-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.

Analogue (Modeling)

Analogue-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.

Waveshaping

Adding intentional distortion to the waveforms to achieve aggressive overtones that are either harmonic or inharmonic. This will help you achieve gritty, bitey tones dripping with character.

Additive

Stacking waveforms and blending their harmonics is key to an expansive range of harmonious, dissonant, and tension-driven sounds. With six operators available, the complete FM experience is possible, including the ability to go back in time for classic sounds you have heard throughout recording history.

Classic FM

Last but certainly not least, Opsix's highly flexible and powerful architecture starts with true six-Operator FM. As a result, it easily delivers signature sounds you have surely heard on thousands of hits from the '80s on through today, and with far more polyphony than other standalone FM synths available today.

With all of these ways to realize and explore sounds, Opsix mk II is uniquely suited as a "future-modern-classic" synth!

Altered Reality

What started as a legacy synthesis has evolved into something completely different. Opsix mk II is FM-based, but the similarities to the classic synthesis end there. The Altered FM architecture delivers sounds across a vast spectrum, far wider than any single synthesis has been able to cover before, thanks to new sound components; new waveforms, filters, shaping, effects, LFOs, envelopes, modulations, and more, all translating to its broad assortment of sounds.

Powerful Effects Processing

Opsix mk II provides three blocks of 30 types of high-definition effects that you can use together to enhance your sounds even further. There's everything from a great mix of usable standard effects like chorus, phaser, delay, and compressor to some world-class shimmering reverbs that will elevate your sound to the next level.

Notes: With the MORPHEUS digital filter module, Rossum are finally able to unleash the full power of the 14-pole Z0-Plane Filters that Dave invented for the E-mu Morpheus synthesizer.

The MORPHEUS Eurorack module includes over 280 filter configurations, which are called Cubes. Each Cube is composed of up to 8 complex filters that you can picture as being at the corners of a three dimensional cube (hence the name). Morpheus gives you the ability to smoothly interpolate between those 8 filters within the cube's three dimensional space.

Due to processor limitations back in the day, the original Morpheus was capable of real-time morphing in one dimension, but interpolation in the frequency and transform dimensions were set at note-on and remained static for the remainder of the note. But even with that limitation, Morpheus offered sonic capabilities that are unmatched to this day.

With the MORPHEUS filter module, you now have simultaneous real-time CV control of all three dimensions, for dynamic timbral effects unlike anything you've ever heard before. In stereo.

Like all Rossum Electro-Music digital modules, all parameters are available for adjustment with a single button press. No menu diving.
