>Here's one that deserves a lot of credit for how accurate it is: https://github.com/chiaccona/VDX7 I read "bit-accurate" and immediately went Ctrl+F "rate": "It then resamples from the native 49khz sample rate", yeah, this one is serious!

If people are interested in the DX7's technical details, I've done some work reverse-engineering it, and some of Yamaha's other FM synths: https://ajxs.me/blog/tag/DX7.html Ken Shirriff has also done some amazing work analysing the DX7's sound chips: https://www.righto.com/2021/11/reverse-engineering-yamaha-dx... A really awesome documentary on the DX7 by MadFame: https://www.youtube.com/watch?v=sXt_NXjc7oY There are a lot of software emulations of the DX7 that are quite realistic, like the amazing Dexed. Here's one that deserves a lot of credit for how accurate it is: https://github.com/chiaccona/VDX7
