Is it possible to trigger samples and loops from GPIO ?

thank you

Yes, but it's a complete different concept: Replace the midi call back with a gpio thread.
None of the builds on this forum support this (I expect severe issues in syncing both techniques).
However, it's a nice but non-scalable, technique for a DJ :-)
I would suggest to use a Arduino generating midi signals instead. Then you have the best of both worlds and a better scaling platform.

What do you mean by scalable? Basically I would like to have lets say the lower or higher octave with few GPIO with loops while having the midi keyboard playing the rest of the mapping...

I incorrectly assumed you wanted to replace the keyboard with GPIO, which could lead to pins shortage :-)
As I understand you now, it's a matter of selective copy/paste of the few note-on/off (message 9 and 8) statements from the midi call back to the buttons thread.
Mind however that triggering from another thread than midi might cause hics in the playing sounds.
