Thank you for purchasing the Korg opsix module altered FM synthesizer. To help
you get the most out of your new instrument, please read this manual carefully.
About the opsix module 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 module 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 module 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 module 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.
• This unit has a note trigger function that lets you use the STEP 1–13
buttons to play instead of using the keyboard.
• This unit supports some MIDI 2.0 functions (Property Exchange), and
can interact with compatible MIDI devices.
About the sound generator of the opsix module
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 Corporation. 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 module 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 module 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.
