mrhythm

I searched and read thru the forum. It's very imformative and encouraging. However, I am still confused about certain things. Here's what I'm trying to achieve: 4 faders/pots 9 encoders 50 buttons I know i need midibox 64E. The question?: Do I need more than 1 core? Do I need the LCD? Do I need the menu buttons? TIA Ben
