So I've been building a 100% analog polyphonic synthesizer with an unique twist. To use only vacuum tube era technology from the 1930s. Over 300 neon gas diodes create the sound you hear. Pretty awesome for technology from 100 years ago. Still a work-in-progress.

OMG! What's that and why it looks so cool 🤣!

That's what happens when you use old technology to build something new. : }
