You can either build the DLLs using the VST SDK or you can just download the DLLs and drop them into the VST folder.
Then open your instrument track and you are moments away from a beautiful DX piano.
Alternatively, on linux there is a ALSA pluging called Hexter with to all intents and purpose IS a DX7.
Finally, I happen to have a Yamaha 76 key keyboard that has a DX7 in it’s GS font.
I wouldnt be surprised if a yamaha piano has this sound built in (they must be rightfully proud of it).
We use a yamaha piano at our church and it has it (throw the mod wheel up and a bit of reverb and it sounds great layered with some other sounds).
But most of the feel of their piano (in the video you ref) is the after effect right?
For example, the chorus, reverb etc … on my Yamaha GS, patch 8 is called DX Piano and sounds a bit like the EP on the video (subjective of course).
If I then use the reverb/hall effects/chorus etc (part of the GS extension) I can make is sound like the later sounds in the video.
I can also throw it thru Cubase effects (MDA also do a series of chorus etc).
Or I pass it thru my Zoom R16 and let it add effect … or my Miniak and let it add effects (or all of the above).
The MDA is tweakable too … so pass that thru effects and you have a reasonable approximation.
Hexter, on linux, is a DX7. Sysex in the patch and it should sound like the piano used (assuming they use the DX7 patch).
You can probably find some soundfonts too that are accurate samples of a DX7 EP. And Cakewalk have given away their soundfont player for free.
Again, throw post-processing at it to change the sound.

Oh an in another forum, someone was asking about Abelton … I downloaded a lite version to try to help setup synth and that had some excellent samples on it. I believe you can get this for free if you buy some relatively cheap kit. IE if you used their trial version and like it … you could get the lite version when buying an effects box
