Hi,
I started noticing very bad digital artifacts from my CP88. They are noticeable expecially with the RD78 sound when releasing notes (but often even on attack).

From what I know, they can be due to errors in sound compression or faulty audio conversion.

Anyway, just to be sure, I already verified that the artifacts are actually coming from the CP88, because I can hear them through headphones directly attached to the keyboard (but I also can hear them - and louder! - through my P.A.).

When I started noticing the issue, the installed OS version was 1.4. I then updated to the last version, but nothing changed.

This is very annoying. What can I do?
The keyboard is still in warranty.

Thanks
