My CP40 seems to be sensitive to low power situations which significantly affect the sound. At a minimum low voltage seems to create poor sound and at worse the keyboard audio cuts in and out.

I have only had this issue on two gigs so far and relocating to a separate outlet solved the problem. Since I use my CP40 as part of my pro rig and perform several times a week, I purchased a voltage regulator expecting it to resolve this issue, but unfortubtely it has not.

Has anyone else has any experience with some form of power conditioning or voltage regulation that has helped avoid this issue?

Thank you
