Hello everyone 
i’m Leon from Germany and I want to design my own midi controller.
It should look exactly like that: http://www.malighting.com/fileadmin/_processed_/csm_MA_onPC-fader-wing-web_04_d5a4263569.jpg
I decided to build the LPC17 based Core and use 2 DIN, 2 DOUT (60 buttons - 60 LEDs) and two MFNG module, because I want to use 15 Motorfaders from Alps.
Is this project possible with midi box?
Where can I buy the PCBs in Germany?
I would be very happy with some feedback
All the best
Hi Leon
Welcome here
Your project is absolutely possible with midibox.
Few notes:
You need 8 DIN/DOUT for 60 button (8x8=64) or a DIO_MATRIX which can handle 64 led and button
I suggest you go for the STM32F4 core, which is the more recent core available for MIOS

Sounds good
But why do I need 4 DIN for the buttons? I thought one module with 4 multiplexers could handle 32 Inputs?
Okay, but I can’t work with SMD, is that a problem with the STM32F4?
Ho sorry you talk about the pcb with 4DIN or 4DOUT , so yes two pcb for led and 2 pcb for button is ok
The only SMD part is the SDcard holder, footprint is large, no special skill to solder this with standard iron.

Ah okay
And where do I get all the PCBs from?
SmashTV aka AVI ShowTech… just google it and you’ll find it.
You can also send me a PM and tell me which PCBs you need. I maybe can help you. I’m from Berlin, Germany.
