I just bought a Minibrute & a Spark CDM that I really dig, and I am using a Macbook Pro (15-inch from Mid 2010, 2.53 GHz Intel Core i5, 4 GB 1067 MHz DDR3, 500GB HD startup disk). What interface can someone recommend? I'm thinking of getting an M Audio just because I had such luck on w/ my old Delta 66 break out box/sound card. I never really need more then 4 ins/outs at once, as I want to record stereo or 4 channel drum tracks to use for a project of mine. Can anyone gimme some input here? Which one? Used or new? Am I going to use Garage Band when I get going? Or is there another software for recording that's easy & cheap? I record in the end on minidisc multitrack recorders. I LOVE the Yamaha MD8 and the Sony MDM X4 (8 track & 4 track, respectively) - but I need to get this Macbook up and running so I can make beds of noise with which to record live drums and vocals/gtrs/bass over on the 8 track (I'm an awesome drummer but shit singer). Any help would be greatly appreciated....
