hi been lurking a lot on the forums and learning little bits here and there...and i've gone through the wiki and the hardware pages. I have an "idea" of what I want...but I need to confirm this. Nothing original here, but I would like to build a controller for ableton. what i would like is buttons (to load clips/samples), pots (for effects) and led's (to make it look pretty :). is this right: for the buttons, i need a DIN for the pots, i need an AIN for the led's, i need a DOUT but for the controller, i'm not sure which I would need as they seem to differ for the modules i would like to use...so if you guys could help me with that, id really appreciate it :D
