I read a lot about midibox (cool stuff!) and want to midify an organ console.  
 
So I think I could make use of MIDIO128. Since I have 3 x 56 (keyboards) + 1 x 30 (pedal board) + 1 x 20 (stops/buttons) inputs, I need the following (if I am right): 
 
- 2 x CORES 
- 8 x DINX4 (2 for every 56 inputs, and 2 for the other inputs) 
 
Or is it possible to connect 4 additional DIN's to a core module, when not using any DOUT's? 
 
 
Another idea tot connect more inputs on a single core module might be using a 8x8 matrix. Are there people who succesfully adjusted/created an application for a scan matrix? 
 
Thanks for your help!! 
BTW: I am a newbie  :rolleyes:  
 
Best regards, 
Edwin
