DIY Midi Foot controller
Posted: Sat Feb 26, 2022 10:42 pm
Just finished a breadboard version of a 16 button midi over usb foot controller, with LEDs using a Teensy 4.0 board.
I have 16 soft buttons in a solo panel, which are full of various scenes, chases, movements and collections - enough for what i need.... for now
Each button sends a note on and note off value to each configured soft button and the LED's are setup so each button press clears whatever was illuminated and illuminates the corresponding button LED. If i accidentally do a double press, togging the soft button on then off, the LED will stay illuminated so i know where to press again
Essentially I've read up on various similar projects and copied/tweaked the code to suit so hopefully it's the right way to do what i wanted to achieve (it works which is a bonus)
hardware and schematics are as below
