Hi Jim,
All I can tell you, is what I use to get the best out of this program. I'm currently running Logic Express 8 on my Mac. The Express version is more than adequate. I don't feel the need to upgrade to the full version, which is much more expensive. If you hunt about for reliable reviews, you'll probably find that Express and the full version are very similar. Some features available in the full version are not present in Express but are unlikely to be used by new users of this software. |I think that I know my way around this program quite well and am able to achieve fairly decent results. There are still features that I haven't fully explored after several years use (I moved from Express 7 to Express 8.)
Anyway, I connect a Line 6 TonePort KB37 to my mac using a USB connection. The KB37 is a sequencing keyboard that I bought about 3/4 years ago for £199. That's a little expensive but I feel that it has given me tremendous value for money. The keyboard has inputs for headphones, expression pedal, x2 foot switches, Digital out, guitar, x2 XLR mic inputs line inputs 1 & 2, stereo inputs 1 & 2 and x2 Analog outs. Don't get bamboozled by all the inputs. I use the headphones, one of the XLR microphone inputs and the guitar input only! The KB37 comes with Gear box software (various effects for vocals, and guitar etc). Within Logic, the effects are superb anyway and I often bypass the Line 6 effects, choosing to record almost everything without effects and apply them later within the Logic environment.
I use Harmon Kardon speakers which plug directly into my mac. They're a bit expensive too but absolutely wonderful. One of the best aspects of my set up is that I only use x2 usb connections apart from leads for my guitar, mic and headphones.
I hope that this helps you a little Jim and that you enjoy using Logic. Think long and hard about spending extra cash to buy the full version of Logic. I reckon Express is more than adequate unless your aiming to become a top notch producer/engineer!
