Korg Opsix Native is a software recreation of the popular Opsix hardware synthesizer, bringing its unique “Altered FM” synthesis engine to DAW environments. This plugin faithfully reproduces the sound and functionality of its hardware counterpart, offering six operators with multiple synthesis types beyond traditional FM, including ring modulation, filter, and waveshaper. The user interface has been redesigned for optimal use as a plugin, featuring a sleek, modern look with animated oscilloscopes for each operator. Opsix Native retains the hardware version’s powerful modulation capabilities, extensive effects section, and the ability to create complex, evolving sounds. With over 250 factory presets and full patch compatibility with the hardware Opsix, this plugin provides a versatile sound palette suitable for various musical genres. The software version also includes additional features like unlimited polyphony and seamless integration with DAW automation, making it an attractive option for both hardware Opsix owners and those new to the instrument.
Pros:
• Faithful recreation of the Opsix hardware with identical sound engine
• Intuitive user interface with animated visual feedback
• Versatile synthesis capabilities beyond traditional FM
• Extensive modulation options and high-quality effects
• Full patch compatibility with hardware Opsix
Cons:
• Relatively high CPU usage, especially with complex patches
• Lack of physical controls may impact real-time performance tweaking
The Opsix Native plugin offers a comprehensive set of features that make it a powerful and flexible synthesizer. At its core are six operators, each capable of generating various waveforms including sine, saw, square, and more exotic options like super saw and noise. These operators can be arranged in 40 preset algorithms or a fully customizable user algorithm, allowing for intricate sound design possibilities.
What sets Opsix apart from traditional FM synthesizers is its “Altered FM” approach. Each operator can function not only as a typical FM carrier or modulator but also as a ring modulator, filter, or waveshaper. This versatility enables the creation of sounds that go far beyond the typical FM palette, from warm analog-style pads to harsh, digital textures.
The plugin’s modulation capabilities are extensive, with three envelope generators, three LFOs, and a 12-slot modulation matrix. These can be applied to various parameters, including operator levels, ratios, and effect parameters, allowing for complex, evolving sounds. The animated envelope and LFO displays provide visual feedback, making it easier to understand and fine-tune modulations.
Opsix Native includes a robust effects section with three simultaneous effect slots. Users can choose from 30 different effect types, including various delays, reverbs, choruses, and more esoteric options like grain shifter and overdriver. These effects can be reordered and modulated, adding another layer of sound-shaping possibilities.
The sequencer section is another standout feature, offering both a 16-step sequencer and a more complex motion sequencer. The step sequencer can control notes, velocity, and tie, while the motion sequencer allows for recording parameter changes over time, creating evolving, rhythmic patches.
The user interface has been thoughtfully designed for plugin use, with a clear layout that provides easy access to all parameters. The operator section features real-time oscilloscopes, giving visual feedback on the waveforms and modulations. The spectrum analyzer and oscilloscope views provide additional insight into the sound being created.
Opsix Native also includes a randomizer function, allowing users to generate new sounds quickly. This feature can be fine-tuned to affect specific aspects of the patch, making it a useful tool for both inspiration and sound design.
When compared to similar plugins, Opsix Native stands out for its unique approach to FM synthesis. While traditional FM plugins like Native Instruments FM8 or Arturia DX7 V focus on recreating classic FM sounds, Opsix expands the sonic possibilities with its additional operator modes and extensive modulation options. Its interface is generally more intuitive than many FM synthesizers, making it accessible to those new to FM synthesis. Compared to other modern FM-inspired synths like Elektron Digitone, Opsix offers more flexibility in its FM implementation and a broader range of synthesis types. However, it lacks some of the sequencing depth found in Elektron’s offering. In terms of sound quality and versatility, Opsix Native competes well with high-end virtual synths like u-he Diva or Spectrasonics Omnisphere. While these synths excel in different areas (analog modeling and sample-based synthesis, respectively), Opsix offers a unique flavor that sets it apart in a crowded plugin market.
This plugin is best for:
• Electronic music producers seeking unique, complex sounds
• Sound designers looking for a versatile FM-based synthesizer
• Owners of the Opsix hardware wanting to integrate with their DAW workflow
• Musicians interested in exploring FM synthesis with a modern, intuitive interface
• Producers working in genres that benefit from evolving, textural sounds
Korg Opsix Native successfully translates the innovative features of its hardware counterpart into a powerful software instrument. It offers a fresh take on FM synthesis, expanding the traditional boundaries with its “Altered FM” approach and intuitive interface. The plugin’s extensive modulation capabilities, high-quality effects, and unique operator modes provide a vast playground for sound design, capable of producing everything from classic FM tones to complex, evolving textures. While it may demand more CPU resources than some simpler synth plugins, the sonic possibilities it offers justify the processing power. The visual feedback provided by the animated displays enhances the user experience, making FM synthesis more approachable for newcomers while offering depth for experienced synthesists. Whether used for creating cutting-edge electronic music, designing cinematic soundscapes, or exploring new sonic territories, Opsix Native proves to be a versatile and inspiring tool in any producer’s arsenal. Its seamless integration with DAW environments and full compatibility with the hardware version make it an attractive option for both studio production and live performance setups. Despite the lack of physical controls, which may impact some aspects of real-time tweaking, the overall package presents a compelling option for those seeking to expand their sonic palette with a modern, powerful FM-based synthesizer.
