I have an 27 inch IMAC I just bought brand new(8 gig ram/I-7) and MOTU 828MKII. I am getting ready for an upcoming recording session that requires me to record 14 piece band with live audio. I was doing a test run at home with my son playing a live drum set with 10 mics set up and me playing guitar to simulate test session before the actual session. With the 11 inputs I was unable to see the waveforms while I was recording, but after I stopped the recording all the waveforms appeared. I did see the little recording box displayed to let me see that I was recording. Is there a setting that you can set for this or do I need more horsepower to keep up. I would like to see what the waveforms look like while I am recording to see if I am peaking out or not.
