4: I\'m in the procees of building my home studio, as of now I only have a
computer with the prgram Reasons (Propellerhead) and my midi input keyboard.
My question is, as of now im not recording vocals or live instruments but
would like to build up with the basic equipment that i can use now such as
mixers,dat recorders,additional software ect.. basically looking to record
music and mix it down.
Reason is a very powerful program and you can really do a lot with it if you know your way around midi. If you want to get into recording audio you'll need additional multitracking software. Anything that supports rewire is the best bet because you can use reason without multiple sound cards and external cables (sounds are routed digitally) You'll have to look at each software program to figure out which support rewire. Again my choice would be to get started with the Mbox/Protools. It's a little bit more expensive than other solutions but the hardware and software are both included and are tested together. Protools works with rewire so reason and protools will play nicely. Getting to know protools can be extremely important if you ever want to work at or with other studios because it's the most common. Another protools option is to look for a Digi001 used on ebay. It's discontinued, but relatively cheap and you can get up to 18 ins and outs (8 analog, 8 adat-digital and 2 spdif digital) while the mbox only has 2 analog and 2 spdif-digital.
As far as other equipment most of what you mentioned is relatively useless if you're running a computer based home studio. Mixers are all done by software and dat recorders are kinda being phased out because computers generally record at 24 bit depth....dats are still used but in the home studio environment it's probably not the best way to spend your money. If you want to spend some money get a few mics, and maybe an additional mic preamp (most protools soundcards have at least 2 preamps)
