Hi I am pretty new to recording. I need an interface and I'm really considering the Apogee Duet, but I have a couple questions. Firstly, I'm not even really that familiar with what an interface is. I guess it takes the place of a soundcard and allows you to have more inputs when recording. Is that all? How good is the Apogee Duet at recording drums? The number of outputs it has is not really a problem for me because I know a pretty good technique for recording drums with just 2 mics. So will it sound alright with the Apogee? Also (this is a really newbie question) since you can record 2 instruments at a time with the Duet does that mean you will be recording 2 tracks at a time? I will probably be using garageband. So if I'm recording drums with 2 mics will I be able to adjust the volume of each mics with the 2 tracks after I record? Finally, my setup for recording will be as follows: My macbook, apogee duet, and a couple shure mics. Is there anything else I need? I heard people say u need a preamp.. but I'm going to be recording guitar and keyboard by micing my amp so do I really need one? Thanks a lot for any help and I'm sorry I am so new at this.
