Superb user interface
Control surface and a rich variety of other 
controllers
The huge array of functions and parameters are 
displayed in a 10.4 inch color LCD for excellent 
visibility. The OASYS uses Korg’s proprietary 
TouchView graphical user interface, letting you 
perform operations simply by touching the screen.
In addition to traditional controllers such as joystick, 
ribbon controller, and assignable keys, there’s also a 
control surface consisting of numerous sliders, knobs, 
and switches.
The control surface provides sliders, knobs, and 
switches that give you tactile control for editing 
sounds via the Tone Adjust function, controlling the 
KARMA function, editing EQ or the volume or 
panning of each oscillator/timbre/track, or adjusting 
the source level for recording or sampling. You can also 
use the control surface to control external MIDI 
devices.
The LEDs located beside the sliders and around the 
knobs show the current status or the stored value for 
each controller, contributing greatly to the ease of use. 
With its excellent set of controllers and superb display, 
the OASYS provides full scope for your imagination 
and artistic expression whether you’re performing on 
stage or working in the studio.
88-key model features the RH2 keyboard
The OASYS 88-key model features the RH2 (Real 
Weighted Hammer Action 2) keyboard that replicates 
the playing touch of an acoustic grand piano with 
heavier action on the lower keys and lighter action in 
the higher ranges, responding to every nuance of your 
playing.
Velocity-sensitive pads
The OASYS provides eight velocity-sensitive pads 
located in front of the large LCD screen. In Program 
mode you can assign up to eight note numbers 
(together with velocity values) to each pad, and in 
Combination mode you can also specify different MIDI 
channels to each pad. The Chord Assign switch makes 
it easy to input notes and velocities in a single 
operation. You can also use these pads in conjunction 
with the input channel settings of a KARMA module, 
so that striking a pad will make the KARMA function 
generate a phrase – yet another technique not available 
when using a keyboard alone. The pads have been 
newly designed for optimal action and best feel in any 
situation from performance to production.
On-board help functionality*
An on-board help function is built-in to assist you in 
taking advantage of the OASYS’ astounding wealth of 
functionality. Illustrated explanations of the 
parameters and how to use the controllers are shown 
in the screen. You can also jump to the explanation for 
a desired function, or move through a history of the 
help items you’ve been looking at, letting you 
concentrate on your work without taking your eyes off 
the screen.

Storage expansion via USB 2.0
Four USB 2.0 connectors are built-in, making it easy to 
expand your storage via external hard disks, 
removable disks, flash media, and so on.
The OASYS’ expandability
The OASYS uses an open architecture that allows it to 
be expanded without adding hardware.
The EXs series of high-capacity PCM library data that 
takes full advantage of the PCM synthesis engine, the 
EXi series which adds new synthesis engines that are 
organically integrated into the entire system, and the 
EXf series which adds new plug-in effects.
An ADAT optical output jack and word clock input 
jack can be added by installing the optional EXB-DI 
(hardware). This sends the eight channels of the analog 
audio output jacks (INDIVIDUAL 1–8) via ADAT 
optical format channels 1-8 as 24-bit 48 kHz digital 
signals. (You can make settings within the OASYS so 
that the MAIN L/MONO and R output is assigned to 
INDIVIDUAL 1–8.) This option also lets you use the 
word clock input jack to synchronize the OASYS with a 
connected digital audio device.
