OK. I am new to Logic. I have read most of the HUGE manual, and after working in the audio industry for over a decade and having a little face time with this app I have to say that Logic 9 is the DAW for me. I love the layout, effects, included instruments, etc. I am currently setting up a recording studio and a live DJ rig and I am on a limited budget. I was thinking about getting a Mac mini for my DJ rig, but that's looking like a no go. Right now I need something I can use on stage and studio. To be clear, I am doing Hip hop stuff, so a lot of VSTs (AUs), plug ins, etc... but not really a lot of tracks. Lots of bouncing down, vocal overdubs will be bounced, etc. I went to my local guitar center, sat in front of an iMac with 4GB of ram and played around for about 20 minutes. I got the System overload error and I was shocked! I was running 6 VSTs.... I'm not sure what the latency was set too, but that's one reason I wanted to go Mac and w/ Logic because I was to understand that core audio and Macs were just awesome. So now I am thinking about a new MBP and honestly kind of on the fence. I can probably only afford 4GBs of RAM at first and upgrade later, and will probably stick with the 5400 rpm drive for now. What can I expect? I know this varies, but is a 128 sample rate with 7-8 VSTs and 6 Vocal tracks with a considerable amount of effects plug ins crazy talk, or is it reasonable? I have heard that the iMacs are out performing even the Mac Pros at the moment, but I am so afraid to have one of those on stage as we get pretty rowdy. I was going to put my MBP in a plexi glass case on my DJ rig with tons of fans and ventilation and use a wireless mouse and keyboard. My final question.... How stable is mainstage? Again, setting up a 30-45 minute set with different VIs and effects.... insane, or can it be done? Some people have said Mainstage is so stable they can count on it day in and out, I have heard others say they have to set the latency so high using a midi controller for keys/synths/samples isn't a reasonable option. Thanks in advance. I am sure I could have scoured these forums for hours to get answers to each question, but with the new MBPs, I was wondering if anyone had any personal tips, ideas, or experience to share. Thanks in advance.
