Advise for a midi foot controller

[markus625]

Hi guys came across this site and opendeck while searching Google.

So I was originally looking at designing a midi foot controller using a Arduino pro micro or similar with a multiplexer.

My goal is to make a midi foot controller to control the tonex pedal .

I would have 5 foot latching switches with corresponding LEDs , and possibly 3 buttons with integrated LEDs like these.

I would need midi in/out a usb and or 9v 2.1 DC connector for power.

And a display to show bank etc

So now I'm confused of what board I need for this project and what multiplexor I would need, a quick search on Google just gives me the CD74HC4067 .

I've read on this forum I need the 3.3v not 5v version .

So some advice would be greatly appreciated.
