Hi, Firstly let me thank anyone who takes the time to read, reply and or help me with my project. I'm planning to build a mbox with the specs listed below and would like to check that I'm on the right path so far... DINs: 119 (115 buttons and 2 encoders) AINs: 64 (21 faders, 41 knobs and 1 joystick) LEDs: 95 I am planning to use the ain64_din128_dout128 application - it supports 64 pots, 128 buttons and 128 LEDs. Questions: Is it possible to stick 1 encoder and 30 buttons on the same DINX4 module? Does anyone know where to get "Led Diffusers" from? I want the ring shaped ones like Allen and Heath use on the xzone:3d, they are very sexy but I can't find anywhere that does them. Can someone please check the following diagram to see if I'm on the right track: thanks again D
