Back once again.. 
 
So, here's what i want to build.. 
 
A controller with 4 faders, 17 rotary pots, 20 buttons (4 of them like push to mute/un-mute for example, and the rest simple ones), 8 LEDs for mute/un-mute, (not sure about this yet) one display, and one off/on button 
 
Please help me with parts list... here's what i figured out so far: 
 
1 Core Module 
2 AIN Modules 
2 DIN Modules 
1 DOUT Module 
--------------- 
4 Faders 
17 Rotary Pots 
21 Buttons 
8 LEDs 
1 Display (maybe!) 
------------------------ 
 
Is this list correct? Do I need anything else? Except for the case obviously :) 
 
Thanks
