I want to remove the chorus from a Karaoke CDG & Video

All our karaoke videos include backing vocals where they are present in the original version.

Regrettably, we do not provide a version of the songs without backing vocals.

Should you require it, you can achieve this using the KFN format and operate it with Karafun Player 2 for Windows.
This is an older version of the KaraFun software that is no longer supported, but if you are interested, you can still download it here: KaraFun Player 2 (Windows only).

Alternatively, you can enjoy the same content with a key change feature via a KaraFun Subscription.
