A fourth Striso prototype is added to the family! It has lots of small and big improvements, better wood, better finish, better electronics, improved sensor stability and some smaller design improvements. Also I made a flat USB controller with the same button board for use as a multitimbral Midi/OSC controller. The quality finally is getting good enough for me to start building a small series for selling or renting out to first early adopters. Please fill in the contact form if you’re interested!
