I touched synthesizers.

A couple highlights:
0:19:50 - Really cool synth arp. Might turn this into a track at some point.
0:34:05 - 303 pattern turns into a Techno rave for 10 minutes.
0:48:30 - This bit until the end is a vibey ending with some random synth tunes I attempted to play.

I hope you enjoy the sounds of modular synthesizers and drum machines and 303!
