David Viens and Plogue have previously tackled the dissection and clean-room replication of three other classic Yamaha FM synths with their chipsynths portaFM and MD. Today they released chipsynth OPS7, and in this video David goes into the nerdy details of how it was put together:
Yes, another video about the Yamaha DX7. But, since it's on this channel, we're not gonna go through basic sound design or the history. [...] What we're gonna do today is show you how the Yamaha DX7 was constructed, what components it used, and how [much of] an incredible, incredible feat of engineering it was for '83.

While I have little interest in all these nostalgic emulations, what is new in this one is actually interesting: feedback per OP, multiple waveforms....

Indeed, my favorite thing about their chipsynth PortaFM (an emulation of Yamaha's two-operator "toy synth" chip from the late 80s and early 90s) is that I had the opportunity to use a nice weghted keybed, velocity sensitivity, a sustain pedal, MIDI, multiple layers, and even increased polyphony via chaining the VSTs together. All with essentially the same sound as the little PSS-140 which served as my first musical instrument. And no broken keys!
Nostalgic, yes, and brutally obsessed with the reproduction of flaws like aliasing or even quirks in the original DAC stage, but also very much doing a service to musicians with the increased accessibility in addition to the preservation of synth history. It's a commercial endeavor, but I think the price is modest for what you get in these.
