this helps with getting the notes accurate, but it really is a huge help to have a lot of practice. as well as constantly referencing the original song to make sure the drums, notes, rhythm, and sfx are all accurate.
how tf can you process so many notes in yor head and know exactly what to do? I just do random sh*t and hope it sounds good. I wouldn't be able to do anything like this. This is amazong and there is so much going on that my cheap af computer cant handle it.
