The ct3 file extension is mainly related to an audio output format recorded using the Casio WK-1800 Keyboard.

It was a type of 76-key portable keyboard with Floppy Disk Drive for song play and storage released around 2003.

This type of ct3 files contains single user tone.

These files can probably only be played using Casio WK-1800.

How to convert:

Possibly could be converted to some other audio format, provided you will find a converter that supports it.
