Hi Darren, I dont know much about the gear/software you are using, but suggest trying a direct line in first and see how you get on.
This is the easiest way to get a clean controllable signal.
Using a mic is no black art, but it can take a lot of experimentation to get the best results, and the set-up is dependent on so many variables, not least room acoustics. Unless you are lucky, you also might find that you are forever chasing out odd intrusive hisses & rumbles.
Sorry, I know nothing about 'logic'. I have never tried using an apogee mic either.
