Hi there, my friend and I want to begin recording at home. We will be recording/using two guitar parts and two vocal parts (lead and backing vocals). We originally decided to record everything separately as this would be much cheaper however we have no decided it would be much easier and worth the cost to record it all at the same time but we are concerned that the microphones will pick up sound from all 4 music parts, rather than than just the one it's supposed to be recording. What im trying to say is, is there away of recording two guitar parts and two vocal parts at the same time in the same room and what do we need? All help is much appreciated, thanks.
