Applies to: X-Station
To do this you need to select the 'Cal Pitch/Mod:' page in the global menu on your X Station (press the 'Global' button then use the 'BANK/PAGE' buttons to scroll through the options).
Once on this page, move the pitch bend joystick from extreme left to extreme right a few times until you see the numbers on the screen changing from 0 to 255 and resting at 128 with the joystick centred.
Then move the joystick through its full vertical range from the bottom to the top a few times, until you see the numbers on the screen changing from 0-127. Once you have done this, press the 'write' button to save the global settings, and this should now be saved.
