Some one told me that a midi module would b good but it sounds stupid to me cuz the files on the modules are essentially the same as on my comp.
Whoever told you that a midi module makes a good preamp probably has no clue what a preamp is. I've also seen questions about preamp plugins.
A preamp is a device that amplifies the low output of a microphone signal to line level so it can then be passed somewhere else in a chain. The next device could be anything like a compressor, eq, reverb or a digital converter to get the sound into a computer or some other kind of digital recorder. Because of what a preamp does, it's physically out of reach of the plugin domain. The most basic explaination of preamp is it's a volume control for your microphone. It's the thing you plug a microphone into. A preamp handles an analog audio signal that gets represented as electricity.
MIDI is a controlling and sequencing protocol that, in and of itself, has nothing to do with passing an audio signal. There is no such thing as a MIDI preamp.
Good preamps have names on them like Great River, API, Daking, Neve, Grace, and maybe Sytek or Sebatron. There are many others. High quality mics and preamps are very important for good results, and technique is even more important.
If you're really starting from scratch I'm a little curious to know what kind of monitors you have and what kind/size rooms you're recording and mixing in as well as if there's any acoustic treatment involved. Having nice gear is important for great results but that's not usually what's holding peoples' recordings back in the initial stages. Mic placement is very important. Gain staging is very important. Room acoustics are critical.
Ever heard of standing waves? Modes and nulls? Comb filtering? Early reflections? If not, you shouldn't have to spend a dime on patch bays and MIDI modules to get better recordings.
