Hello,

For my second teensy project, 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.
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 ?

Thank you for your help,

Abel
