Korg X5DR X5D Soundbanks

The contacts are probably dirty or bent. The keyboard is relatively easy to remove if you have any experience.

Check the output socket for corrosion, this would stop the sound from getting to the amp. Plug in an output cable and wiggle it around to see if it works intermittently. Plug it in and out a few times and see. We are looking for a dirty connection.

There's a watch type battery (flat disc) on one of the boards inside the X5D. This maintains the settings while the keyboard is switched off and could be the whole problem.
The keys are on two different circuit boards connected with a multi-pin cable. If the cable were dislodged I would expect it to simply cut off half the keys but it's probably worth checking.

You need a reprogramming done from the Maker . Contact Authorized Korg Service center . Be away from frauds.

On page 105 of your X5D manual, read up about "transpose". Setting the transpose shifts the notes plus or minus from the normal.

If you don't have a manual, you can download one for free.
