I recorded vocal using the Layer function. Created two tracks as I wasn't able to sing whole song at once. The things is that I noticed that each layer moves at the same time. So, I can't pin which I like. I'm not sure if my explanation is clear, so I attach the screenshot for the reference.
eg) I prefer the Layer 1 at the very first part and prefer the Layer 3 at the next part. But if I move the Layer 1 then I can't use it any longer. Can I lock it or something?
