Hey, I just created an account cuz I've always been extremely interested in building one of these things. I am possibly getting the parts to build this or an i7 and new motherboard and ram for my graduation present, and I thought I'd do a little research to help figure out how to go about building a Midibox 64e. I am wondering if it is possible to build a Midibox 64e without any DOUT modules. Sounds absurd? I don't really care much for having LEDs and I don't know of any other uses for the DOUT module. The reason i would like to go with the 64e instead of the normal 64 is cuz with the 64e I would be able to use encoders and I think that would be a really useful thing to have. So is this possible? And if it is am I being an idiot for considering not using them? Thanks for the help in advance -Connor (If someone says "GOOGLE" or "SEARCH FUNCTION" I already tried both for about 30 minutes lol)
