Hi! so...i'm about to buy my first MIDI keyboard, for use with garage band...the only reason i hesitate is because the keyboard does not have any drivers...maybe i don't need any, though? When I look at new keyboards/controllers, though, they all seem to come with CD/ROMs, which suggests that there is something needed to connect keyboard and computer?) my thought is to buy a MIDI interface: either this http://www.m-audio.com/products/en_us/Uno-main.html or http://www.m-audio.com/products/en_us/MIDISPORT1x1-main.html (btw, can anyone suggest why i should prefer one of these over the other? to the eyes of a newbie they seem to do the exact same thing! the only difference i noticed was that the midisport has "16 discrete MIDI output channels" whereas the uno's channels aren't "discrete"...should i care?) and then hook-up the keyboard to my mac through that...am i missing something? have i simplified the process? any thoughts? suggestions? recommendations?
