DIY MIDI Controller Project

[belae1ka]

Hello,

For my project I am creating a DIY MIDI DJ mixer. I am using this link as a reference;
http://www.instructables.com/id/A-Fr...tylish-Modula/

My mixer will consist of;
--21 potentiometers
--5 slide potentiometers
--43 buttons
--3 rotary encoders
--one large display
--two 4-digit 7-segment displays
--Various amount of LED's

That's a lot of I/O pins!!!!

I plan on using Teensy 3.6 MCU's.

My question is, can I interface multiple MCU's in my project in order to account for all the I/O pins?

-If so, this would theoretically help me reduce as much time delay as possible right?

Thank you.

-Kevin

You can use SPI or I2C to daisy chain microcontrollers, but I imagine one Teensy 3.6 is powerful enough to handle all these components. You can use shift registers to reduce the amount of pins needed on the Teensy.

O man please no don't chain these things just use multiplexers, check out my build post here to see how I did it.
