I've been watching videos on youtube about how to make them, But the majority of videos go to the site called Ultimate Guitar.com But they don't have the songs i want? Is there an alternative? 

http://www.songsterr.com/ You have to create an account to download the GP file, but they have some songs that UG don't.

Also on Songsterr you can download the Guitar Pro files of the songs, if you can find them there.

I've also found a few on other sites by just googling: artist - title guitar pro.

 

If there are really no tablatures there is no other option than getting a copy of Guitar Pro and charting it yourself from maybe text tablatures, a tablature book or recognizing the notes.

 

Also I have to move this topic to 'Help & Support' since this forum to ask people to help you with some specific part of a CDLC like testing it. Maybe creating a tone for you.
