Korg Opsix - FM Synthesis Evolved
Opsix offers a complete re-imagination of FM synthesis with an enhanced user interface for easy and intuitive control of operators, algorithms and an abundance of new features such as different waveform types and the addition and fusion of subtractive synthesis. The instrument lets you focus on exploring instead of getting lost trying to focus on sound creation. Korg have made the Opsix a user friendly sound tool for anyone no matter whether you understand FM programming or not.
Main Opsix Features
- True six-operator FM synthesis, and more
- FM exploration, easier than ever
- Full editing with the DATA ENTRY rotary encoders
- Five operator modes that expand FM synthesis
- 40 preset algorithms and user algorithms
- Three EGs, three LFOs and 12 virtual patches offer an extensive range of modulation
- Eleven powerful filters, including MS-20 and Polysix
- Up to three simultaneous high-definition effects, 30 types
- Visually-satisfying editing with a spectrum analyzer and oscilloscope
- Powerful 16-step polyphonic sequencer
- Add unpredictability to sounds with the Randomize feature
- Favorite and smooth sound transition (SST) functions
- Compact design featuring a 37-key keyboard
Five Operator Modes - Expanded FM Synthesis
Operator modes on the opsix are used to generate sounds that are completely outside what a traditional FM sound generator can make. The operator modes let you create sounds using modulation other than FM. The opsix offers you a much wider range of sound creation, letting you combine the five operator modes (FM, ring modulation, filter, filter FM and wavefolder) and select from a wide range of waveforms.
40 Algorithms
An algorithm controls how the carriers/ modulators work together. The Korg Opsix is equipped with 40 preset options and a further 40 user slots so you can create a whole range of sound algorithms and switch between them instantly.
Free Software Apps
The opsix comes with a diverse variety of music software from Izotope including "Ozone Elements" which lets you not only create songs but also master them using AI, "Skoove" which will help you improve your keyboard playing skills, "Reason Lite" DAW software, as well as software synths from KORG and other brands.
