We finally figured it out.But yes, you plug your instruments, or mic it...and record into the machine. There's a certain procedure you have to follow though.
Then you can always go back and edit it if you dont like something. Once you get all your tracks in, you have to do a mix down. You can add effects, fix the tone ( mids- hi's- lows etc).totally produce it up, same as in a studio. Many options.
once you do the mix down, you can use the internal cd burner, and burn yourself a copy.
