Very cool! This might be a good time to mention a JavaScript emulation I made of the EMS Synthi A, which was also present at the BBC Radiophonic Workshop (well, the closely-related EMS VCS3 was) and contributed, among other things, to some SFX for Doctor Who: https://github.com/AlexNisnevich/synthi-js

This was a project from 6-7 years ago and I had to rely on a third-party library for the web audio bits. If I re-did it today, I'd definitely do it all in native Web Audio.
