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.

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.
