I want to build a rack set up. I have no idea where to start. This is my set up right now. I'm running Ableton Live on my PC with an Alesis MuliMix 16 channel firewire mixer. I run plugins for effects. I hate plugins, and want less wires running across my desk. so I think a rack is the way to go. Am I right? I have no idea how a rack is set up. or the minimal pieces I need to buy to make a humble rack set up. help me!
