mixing two modulation sources together, multiplying
one modulation source by another, or modifying the
shape of the modulation source in various ways.
Detailed Specifications
• Advanced Vector Synthesis: Use the vector joystick
and vector envelope (tempo synchronization
available) to control the oscillator volume, synth
parameters, or effect parameters.
• Single/double structure: Single=OSC1 only,
Double=OSC1 and OSC2
• Oscillator: To each oscillator you can assign a
multisample or wave sequence with four‐level
velocity‐switching, crossfading, or layering.
• Filter: Two multi‐mode filters for each voice (low
pass, high pass, band pass, band reject), with four
filter routings (single, serial, parallel, 24 dB)
• Driver: One non‐linear driver/low boost for each
voice
• EQ: Three‐band EQ for each voice (mid‐sweepable)
• Modulation: For each voice, two envelope
generators (Filter and Amp), two LFOs, two key
tracking generators (Filter and Amp), and two AMS
mixers
• Other: Pitch EG, common LFO, two common key
tracking generators
An effects section with up to sixteen
effects available simultaneously
The OASYS provides twelve insert effects, two master
effects, and two total effects, all available
simultaneously, and all providing stereo input and
output. There's also a Common LFO that can be shared
by these effects, for example to synchronize the
modulation of separate types of effect such as phaser
and chorus.
The three‐band EQ provided on each timbre lets you
make tonal adjustments without using up effect
processing power. In Sequencer mode, three‐band EQ
is provided on a total of 32 tracks (MIDI + audio),
giving you detailed tonal control over each track.
Eight types of chorus (including four‐stage and eight‐
stage types), high‐resolution reverb that models even
the shape and material of the wall surfaces, startlingly
realistic modeling effects (such as guitar/bass amps)
using Korg's proprietary "REMS"* modeling
technology, and mastering effects are all provided,
giving you a total of 185 types of high‐quality effect
that can be used as insert effects, master effects, or total
effects, and applied to individual timbres, to an entire
ensemble, or to your completed song.
These effects can be configured easily and efficiently
using the OASYS' powerful mixer that gives you
complete routing flexibility.
You can also apply effects while sampling or during
hard disk recording.
What is REMs * ?
(Resonant structure and Electronic circuit
Modeling System) is Korg's proprietary technology for
digitally recreating the numerous factors that produce
Main Features Open Architecture Synthesis Studio
and influence a sound, ranging from the sound‐
production mechanisms of acoustic instruments and
electric/electronic musical instruments, to the
resonances of an instrument body or speaker cabinet,
the sound field in which the instrument is played, the
propagation route of the sound, the electrical and
acoustic response of mics and speakers, and the
changes produced by vacuum tubes and transistors.
Detailed Specifications
• Insert effects: 12 processors, stereo in/out
• Master effects: 2 processors, stereo in/out
• Total effects: 2 processors, stereo in/out
• Timbre EQ: Three‐band EQ for each timbre
• Effect types: 185 (every effect type is available for
Insert, Master, or Total effect processors)
• Modulation: Dynamic Modulation, Common LFO
• Effect control bus: Stereo side chain (compressor,
gate, vocoder, etc.)
• Rec bus: two stereo buses (routing settings for
recording and sampling)
Programs, combinations and drumkits
The carefully constructed programs and combinations
take full advantage of the OASYS' synthesis engine,
KARMA function, control surface, vector joystick, and
other controllers.
The drum programs utilize long stereo samples to
ensure natural decays, especially for cymbals. Velocity
crossfading allows seamless changes in playing
dynamics, giving you a full range of expression from
delicate to dynamic. Drum kits are used by assigning
them as the oscillator for a program.
Programs/combinations/drumkits:
• 1,664 user memory programs (904: 640 HD‐1 + 256
EXi + 8 EXs2 preloaded)
• 1,792 user memory combinations (384 preloaded)
• 152 user memory drumkits (40 preloaded)
• 256 GM2 preset programs + 9 GM2 drum preset
