The EMS Synthi A was small portable synthesizer first built in the 1970’s and made famous by Brian Eno, Pink Floyd (think “Dark Side of the Moon”) and Jean-Michel Jarre. It’s most unusual feature is the matrix style patchbay which allows you to connect anything to almost anything else. Alex Nisnevich has built an incredible Synthi emulator completely in Javascript which you can play from your web browser. It’s a lot of fun and definitely worth checking out!
