Solution
Make sure that (1) the power cable is plugged into the outlet, (2) the cable is plugged into the connector on
the back of the instrument, (3) and is not damaged, (4) there are no problems with the mains.
Is the STANDBY LED turned on?
If the power still does not turn on, contact your dealer or the nearest KORG Service Center.
Is the MASTER VOLUME knob of the Pa900 set to a position other than "0"?
Is the Spearkers parameter turned off? Turn it on.
Check the connections to your amp or mixer.
Make sure that all the components of the amplifying system are turned on.
Is the Local parameter set to off? Turn it on.
Is the Attack parameter value too high? Set it to a lower value, to let the sound start faster. Is the Volume
parameter too low? Set it to a higher value.
When the SPLIT LED is turned on, the keyboard is divided into a Lower part (lower notes, below the split
point) and an Upper part (higher notes, above the split point). Is the Lower track muted? Unmute it.
Do the USER banks contain modified data? Load the appropriate data for the Song or the Style you wish to
playback.
Has one of the USER Drum Kits been modified? Load the appropriate Drum Kits.
Have the Styles or Performances been modified? Load the appropriate data (Styles or Performances).
Make sure that the Damper pedal calibration is correctly set.
Make sure that the Clock parameter is set to Internal. If you are using the MIDI Clock of another device, you
must set the MIDI Clock parameter to MIDI or USB (depending on the port the Pa900 is hooked to the other
device through) and make sure that the external device transmits MIDI Clock data.
Make sure that all MIDI or USB cables are connected correctly.
Make sure that the external device is transmitting through MIDI channels enabled to receive in the Pa900.
Make sure that the MIDI IN Filters of the Pa900 do not prevent the reception of messages.
Make sure that the Drum track is set to Drum Mode and the external device has not transposition applied.
This is part of the sound, and not a problem.
The selected Performance, Style or STS recalled the effect "17 St. Analog Record", simulating the noise of a
old vinyl recording.
Is the USB cable correctly connected?
Is the USB device correctly powered?
Is the device inserted correctly?
Is the write protect tab of the disk or card in the protect position? Unprotect it.
Is the device formatted?
Is the device inserted correctly?
Is the write protect tab of the disk or card in the protect position? Unprotect it.
Is the device inserted correctly?
Does the device contain data compatible with the Pa900?
The USB device is probably defective, due to a short circuit, and cannot be used. While this will not damage
the Pa900, it is advisable to remove the device.
