Guitars & Bass go wirelessly to analog mixer strips, strips direct out to audiointerface + send to rocksmith cables. Audiointerface in mac to mainstage3, mainstage3 outputs back to mixer, mixer outputs to surround system where I can choose how much which instrument goes in which speaker. Rocksmith ingame instruments muted.
Used to have mainstage3 file for every song, but it's too tiresome to make one for every song, now I use one file which has 2x clean 2x distortion channels. Double channels are clones that have same options, but have different memory for settings. Channels have 5 different amp options and 5 different pedals + wah + whammy, controlled with fcb1010. If I had money I'd figure out a way to add 2 or more expression pedals, one to control output volume and one to control gain. Maybe just another fcb1010 and and maybe get Boss Ac3 or alternative.
I got 88" projector, 2-3 people can play simultaneously jumping about. I've adjusted volume of every song, ReplayGain is enough for 99% of the songs and rest are adjusted by ear. Without doing so, I'd need to adjust guitar and bass volumes during every song and I'd just rather not.
I suppose I don't need the rocksmith cables anymore, but they're not in my way so I haven't had a reason to change anything. Didn't the multiplayer require that one player is connected somehow or something?
