Using the OASYS Internal Calibration Application

Important precautions

BE VERY CAREFUL!

DO NOT TOUCH ANY BUTTONS OR CONTROLS

OTHER THAN THE ONES NOTED BELOW.

TOUCH ONLY ONE CONTROLLER AT A TIME. DO

NOT MOVE MULTIPLE KNOBS OR FADERS.

Dismissing error messages

At any point, if you move a different controller from the one that the application expects, an error message will appear. If this occurs, simply dismiss the error message by touching the screen, and then continue.

When is calibration necessary?

Each OASYS is calibrated before leaving the factory, using this hidden, internal application. The resulting calibration data is stored on the internal hard disk.

In general, it should not be necessary to re-calibrate, unless:

• controls have drifted over time (possible, but is not expected to be an issue), or

• the OASYS hard drive has been formatted.

Formatting the OASYS hard drive erases the stored calibration data. Without this, physical controls may still operate correctly–but to ensure the best performance, it will be necessary to re-calibrate.

This is one of the reasons that Korg recommends against formatting unless it is absolutely necessary.

Calibrating the physical controls

1. Turn on the unit, wait for the Combi screen to appear.

2. Press and hold the following four buttons, in the specified order, so that at the end all four buttons are held down: EXIT, 2, ENTER, and FUNCTION.

(Other orders will work, but one in particular - starting with ENTER + 2 - brings up a dialog box first, and appears to put the system in a slightly strange state.)

3. Wait for a few seconds, until some strange text appears on the screen, over-writing the main display. (For those who are curious, these are

Linux command-line messages.) You can release the buttons at this point.

Wait about 10 more seconds. At the end of this time, the test application appears.

The calibration application includes a S/PDIF I/O test, and at startup it automatically checks to see if a

S/PDIF cable is connected. If not, the screen will display a prompt: “Connect S/PDIF Cable.” For calibrating the physical controls, it’s completely unnecessary to have S/PDIF connected–but you’ll need to dismiss the message before proceeding:

4. Touch anywhere on the screen to clear the Connect

S/PDIF Cable message.

Note the text “Fan Control” at the top of the screen.

This shows the current test section.

5. Press the INC/DEC key to browse through the test categories (the name is shown on the top of the screen).

You will step through “Switch & LED,” “LCD,” and then “A/D Converter.”

6. Stop when you see the “A/D Converter” category.

7. Press the front-panel ENTER button. You'll enter the “Ribbon Controller” section.

8. Press your finger along the full width of the ribbon, from left to right. “OK” will appear on the screen.

9. After seeing 3 OKs in all, lift up your finger, and press ENTER. At this point, the calibration data for the ribbon is updated.

For all of the controllers below (except the rotary encoder), follow the same procedure: move the controller to its extreme max and min positions until the display shows OK for all values, and then press

ENTER to proceed to the next section.

You can also use the FF>> and <<REW buttons to move back and forth between the tests. If you find that you are unable to get an OK message for a particular test, use FF>> and <<REW to exit and re-enter the test, and try it again.

10.Joystick: move up and down, left to right.

11.Vector Joystick: move all around, in a circle.

12.Knobs, faders, and value slider: move each one to its max and min positions.

13.Rotary encoder (value dial): this test is slightly different. Rotate the encoder clockwise to

exactly

+30, and then counter-clockwise to

exactly

-30.

14.Tempo knob: move to max and min positions.

After the Tempo knob section, the tests proceed automatically to the foot switch/pedal section. If you do not have all three foot switches/pedals connected, you can complete the calibration simply by turning off the power.

Calibration data is stored after each test

The calibration data is stored each time you press

ENTER after completing an individual test. If you only need to calibrate the Ribbon, Joystick, and Vector

Joystick, for instance, you can simply turn off the power after pressing ENTER at the end of the Vector

Joystick test.

Aftertouch calibration (76-note only)

For 76-note keyboards only, aftertouch calibration is in the “Key & AfterT” section. Calibration for the 88-key is completely different, and not accessible via this application.
