On “Yamaha DX7 Technical Analysis”

Plogue, a Canadian software company, have recently released a (software) emulation of the DX-7 in excruciating detail. Here you can see part of the trouble they went through: link to this video . Suffice to say that they used a logic analyzer to discover gritty details that no other analysis of the DX-7 I know has ever paid attention of.

On “Yamaha DX7 chip reverse-engineering, part V: the output circuitry”

Maybe the closest free plugin, but it's not on the level of accuracy as Plogue's Chipsynth OPS7, which is bit-accurate. The author has an interesting video here, with more to come hopefully: link to this video

On “Reverse-engineering the Yamaha DX7 synthesizer's sound chip from die photos (2021)”

I would recommend Plogue's OPS7, they have put considerable amounts of time and effort into reverse engineering the original chips. The interface is a little clunky but it sounds fantastic. link Edit: a YouTube video about the reverse engineering process from David at Plogue: link to this video
