I have done all my research on MIDIBox and the new PIC18F452/MIOS but I still have what I think in all reality a stupid question but here goes :-[ I'm building MIDI controller for Ableton Live. At it's core will be: (1) Core Module (18F/MIOS) (2) A_IN Modules (64 pots) (2) D_IN Modules (64 momentary buttons) (2) D_OUT Modules (64 LED's). my question concerns the the D_OUT modules and the LED's. I'm confused on the exact application of this. Does this allow me to have LED's turned on/off with the press of a momentary switch? Basically I want each of my 64 buttons to simultaneously toggle an LED on/off with subsequent presses. Is this an application that I can program the MIOS to do? Thanks, Brian
