Woah Dude... You got your work cut out for you in the next few months. Forget about your families and friends ;D , coz that is a major project. ;) I know its sounds exciting, but keep in mind these projects takes a lot of time plus money. ;) Well first off, do this, before commiting to this project: 1. Prototype out your user interface layout. i.e. switches and pots, & encoders. Draw the actual pots and switches on a big cardboard box, this helps alot. 2. Count how many inputs and outputs, then you'll figure out your total modules. DIN's/DOUT's etc. 3. Read the funny but informative n00b 4 dummies: http://www.midibox.org/forum/index.php?topic=3650.0 4. If you are still conviced that this project is for you... Start ordering your kits and stuff. ;D enjoy!!
