Strange sound when playing recorded vocals.

[kale]

Hello!

I've got a really annoying problem. Don't know what to do, searched for the problem but with no result.

I've had Logic for maybe a year, so I'm pretty new to it.

 

The problem:

When I record vocals and playing back for the first time, it sounds like it should do. No strange sound or crackling thing.

But after a while.. It always is some crackling kind of sound at some parts.

 

I discovered the problem when I started using flex-pitch. Immediately the vocal track sounded very strange at the parts where I sing with distortion. It's like laggy/crackling kind of sound. And the stupidest thing is when i undo everything, the annoying sound is still there.

 

Then i recorded new vocals cause I got frustrated. Then I just left it with no editing. Well.. It sounded great for a while. But even when I didn't touch that vocal track it started sounded weird after a while at the distortion/rasp part of the vocal track.

 

But when I double press the track and hit "file" and listen there. It has no strange sound or anything. It sound like it should do.

Does anyone know what causes this problem?

 

Down below - some info about my Logic version, settings and setup. I'm not sure if its relevant or not.

Did you ever find a solution to this? Every time I try to use flex my audio becomes staticky and sounds horrible (even before I apply any flex changes). I'm using 10.2.4.
