The EMM has 6 SHARC DSP chips running hand-crafted parallel DSP code. There are likely very few PCs, if any, that could handle the CPU and are not built with the memory architecture or parallelism used in these devices. If that GPU DSP compute project works out, then it might be theoretically possible to do something similar, but a software version of the Eagan Matrix is unlikely to ever happen.
But if you have an EMM, Osmose, or Continuum (or considering one) you can integrate it with Rack using my upcoming HC one plugin. See pachde (#d) HC-One - Plugins & Modules - VCV Community (vcvrack.com). I have a new release coming in the next few days.
