It could be a problem with my interface, because I'm only recording synth stuff, and it even if the stuff is almost silent, it gets louder and stays clipped for about 3 seconds, then fades back down to almost nothing. Don't think that's normal. But also, if I plug speakers directly into my synth, this weird volume thing does not happen, which is why I thought it might be a problem with my mixer. I'm going to try plugging my synth directly into the interface and not using the mixer. I'm hoping that will get rid of the volume changing.
