Thank you for purchasing the Korg opsix SE altered FM synthesizer. To help
you get the most out of your new instrument, please read this manual carefully.
About the opsix SE manuals
The documentation for this product consists of the following:
• Quick Start Guide (what you're reading)
• Owner's Manual (PDF download from the Korg website: www.korg.com)
Main Features
• The opsix SE features an FM sound generator that produces complex
harmonics by rapidly modulating the basic waveforms of its oscillators
using other oscillators.
• In addition to FM synthesis, the opsix SE also features various operator
modes such as a ring modulator, wavefolder, effect and so on. The six
operators can be combined to create a wide variety of sounds.
• You can use the operator mixer (with sliders and knobs) to directly
control the parameters of each operator. This is useful for intuitive editing
and making dynamic sound changes when you are performing.
• The opsix SE includes a rich selection of filters including Polysix and
MS-20 models, which covers the bases for making sounds like those
generated with subtractive synthesis.
• Three high-definition multi-effects are available, and you can select from
30 types for each.
• 500 programs can be called up and saved in an instant.
• Powerful 16-step polyphonic sequencer.
• A spectrum analyzer and an oscilloscope that let you visualize your sound.
• The opsix SE features a 61-key keyboard with aftertouch. Aftertouch is an
effect that's applied when you play a key and then press into the keyboard
further while holding the key down. The more you press into the key, the
stronger the effect. Aftertouch is generally used to control the volume, the
sound (cutoff frequency) and the LFO sensitivity.
About the sound generator of the opsix SE
The principles of FM sound generation
were discovered and established by Dr.
John Chowning at Stanford University in
the 1970s, when he was experimenting
with vibrato. FM sound generation was
later packaged into an LSI chip and put
into practical use by Yamaha Corpora-
tion. From the beginning of the 1980s, FM
tone generation was used as an internal
sound source on the Yamaha DX series,
personal computers, game machines and
cellphones.
• Operator (modulator, carrier)
The FM (Frequency Modulation) sound
generator is based on synthesis elements
called "operators." Operators are
modulated using simple input waveforms
such as sine waves, outputting sounds
with complex harmonics. Operators can
act as either a modulator or a carrier. The
output sound from a modulator feeds into
another operator and modifies that
operator's output. Carriers receive the
output sound from modulators and
output the modulated result as audio.
• Algorithms
In the FM sound generator, the
combination of the roles and connections
of the operators is called an "algorithm."
Selecting an algorithm is a good starting
point for creating sound. The opsix SE
sound generator includes six operators,
and 40 preset algorithms are provided.
You can use the user algorithm function to create new combinations as well.
• Operator modes
Although the basis of the opsix SE is the FM sound generator, you can change
the operator mode to perform different kinds of modulation besides FM. The
combination of ring modulator, filter, wavefolder and effect makes it possible
to create new kinds of sounds that surpass the range of typical FM sounds.
