I'm trying to put a truly mobile recording studio together. *In my possession at this time I have an iPad2, an old midi keyboard, and I just ordered the Alesis Studio Dock. * My next purchases are gonna be the KRK RP8 studio monitors and a Shure SM57 microphone. So my question is what else do I need to get to yield professional results? A mixer perhaps? Maybe different monitors or different mics? I'm a musician but I'm pretty new to the recording/producing side of things. *I have an iMac at home, which runs Logic, but *I want to be able to record at my friends house along at my own house, or even go somewhere with beautiful scenery and lay some vocals down. *I really dig the apps and the user-friendliness of the iPad and would really love to utilize it's advantages. Thank you for any help.
