Hi, I am just wondering... I have a powered mixer to run my mic's,keyboards,guitar. Will i be able to run that into the line in, and record and be able to hear the sounds live through the software. I can on my PC using Sonar but i used Cubase on my G5 and could only hear after i recorded, which is worthless when recording. Also i have keyboard that is running into my mixer, will i be able to use the GB sounds with that? Any help would be great.
