Hey Justin, thanks a lot.. My intent is to do 24 faders, since that is the max. I actually wanted to go for 32 or 48, but I think the max is 24, right. So for a 24 fader set up with mute buttons(w/LED) and Automation status buttons (w/LEDs) I would need: 3 cores 3 mf 2 din 2 dout right?? where do I buy this stuff?? (never mind, already found it ;D) thanks again Gil
