Like an electric guitar, but with tines instead of strings. Can’t say I’m impressed by the sound, but the concept is cool!
This one on the other hand sounds very interesting! I’ve been playing around with a concept like this myself in the past (although with the modular / Rings)
Looks like a drum machine, but is rather a quirky and glitchy percussive sound generator that you control with a sequencer. Sounds a bit like an Atari Punk Console on steroids. More info here: https://neutral-labs.com/scrooge (including videos).
