Is this possible or are they only meant for encoders?
In the web-ui under hardware > wiring i can see that the standard 4 buttons could be assigned to midi notes tho.
I am using a headless version so nothing is connected yet to the gpio… i must order and use the extra MCP23017 chip to get this functionality?
What library is used to communicate to the gpio?
You can configure any GPIO (RPI or MCP23017) to send MIDI note. The 4 first switches can’t be configured like this because they are reserved for UI operation, but the all extra switches can be configured as you need.
