actually that was old pro tools, any interface works now but you need the stupid ilok thing like some of the more expensive plugins.
Listen dude, you need to at least get a rough mix going, lay down something, anything at your crib before you go spending money on a studio real talk, you sound clueless about some things(and thats ok), if and when you go to the studio, find maybe a local producer.....there will be an engineer at the studio but an engineer is not a producer, in hip hop we get credit for making beats but the true purpose of the producer is to get the best "you" possible, what you think in certain situations might not be the best as far as a song goes, he is like the director and you are the actor, you can bounce ideas off of each other.
Im not sure of your budget, but like someone said if you are serious you could build your own little mini studio, it would involve some room treatment and other things though....
The difference would be that a good studio would have and should have a incredible microphones, the engineer, based on your tone of voice would then choose the best microphone to compliment you. His only job is to record your vocals cleanly and get the best sound. The recording process is the most important process, sometimes the recording engineer is the mixing engineer or sometimes they are different people.
Dont get ripped off, your record should be properly mixed, and a proper mix takes time, not 1 or 2 hours. At the very least I would say 8-12 hours.....and maybe even more depending on what the track is doing and effects used....
Anyway if you do lay down your stuff and dont have money for the mixing, you could send it to me for free, im currently going to school for it and am looking to gain as much experience as possible....
good luck friend.
