It is possible? I want to have communication through the ports of the digital raspberry, without osc / midi
I think the easiest way to do this is to write a separate piece of software which talks GPIO and can translate to OSC to send to Sonic Pi. Something in Python combining GPIO Zero and an OSC library would do the trick 
You may find some of the ideas in this article useful.
Grateful, but I do not have much knowledge of how to build programming
Grateful, grateful for progress
