Hello,
I'm building a midi step sequencer with 16 * 8 buttons with LEDS just for the steps.
At first I was thinking using 8 multiplexers (CD74HC4067 16 channel) but I just learnt about the Keypad library.
I think it could make the wiring a lot easier/cleaner with a matrix
Is there a way to make it work with a 16 channel multiplexer for the columns and 8 digital pins for the rows ?
If no, is there any better solution ?
On this project I also have 32 more buttons, 8 potentiometer, 40 RGB LEDS and 1 ILI9341 screen that's why I'm bit short on I/Os.
Using a Teensy 4.1 for this project.
Thank you for your help !
