Yes, each track is recorded async/separately. When you record, you do it on top of what's already been recorded. You can change the mix, but only the original

Yes, each track is recorded async/separately. When you record, you do it on top of what's already been recorded. You can change the mix, but only the original song "creator" can persist that change permanently. If you want to create your own mix, you can copy the song into a new one that you control fully (mix, remove people, etc.). BTW you can do that with any song already there.
