I want to start my own home studio so I can make an album. I have learned that the best type of home studio for me is a midi studio because it is cheaper then the other ways of making music. I want to buy a computer for this purpose that is not too expensive. I want to purchuse it from the dell.co.uk. What computer do you think is good for this purpose? What mic is good to buy that is able to record crystal clear vocals digitally? I used a bad microphone and recorded my voice on the windows record playerand when I played it back I heard a buzing noise accompanied with the vocals. What is this. What is a sequencer?

What do equipment do I need to make good strong beats. My musical fortay is rnb/hip hop/crunk/bass/electronic. I want to make good quality music. Money is not a worry for me? So any sugestion that might be expensive are welcome. What is a drum machine?
