I have the internal audio. I wish I could just hook up an audio interface to my brain for that sometimes as it would be so convenient for making new music.

In theory I could translate it to a DAW (but I'm not that great at transcribing music...it's possible, kinda, but slow), but I can't easily repeat the music in my head (not what I make up at least, proper released songs tend to be easier to repeat), so it would be difficult to recreate it enough to be worth the effort.
