It won't take mics. Those are line level inputs. You would want a small mixer to plug your mics and whatnot into, then plug the outputs of the mixer into the soundcard. The RCA plugs are digital inputs, not audio. The are for hooking up, for instance, a guitar model unit like a POD or something that has coaxial SPDIF (digita) outputs.
Midi is a data protocol that is used for controlling things that will respond to midi inputs, or will produce midi outputs, like a synthesizer. Midi data from a sequencer will consist of note on, pitch, duration data to make the synth sound a note. It is NOT audio, though, it is data that makes the synth put out an audio note.
Lastly, the Audiophile only records 2 analog tracks (or 1 stereo track) at a time. If you want multiple inputs, you will need something like a
Delta 1010 that has 8 analog ins and outs.
