Wow, this seem great. I know pretty much nothing about making music, but I've wanted something that I can stim with that's nice and tactile, but also makes sound depending on how it's touched. I looked at Glo, The Polyphonic Whale, but never got one. I have an Otamatone, but don't like how I can't do more than one note at the same time (no chording).

This plus headphones seems like a fun time!
