Thanks findbuddha for the reply, i have been looking at the examples "MIOS32 C Interface" think its the same as the tutorials page, the system i would like to build will use all 128 of the digital in's (be good if there was slightly more so i could use all encoders and switches instead of pots) and 1 fader for fading between decks, thank you heaps for the links :), and any further help is much appreciated.
kind regards Highpow3rpc
