I don’t know of options in the modular domain, but an interesting VST option is Infinite Pro http://wolfgangpalm.com/infinitepro.html
I believe all the Palm VSTs are being transitioned over to Plugin Alliance / Brainworx
(Later) ... so I went back and watched that video. Very interesting and also well done. Personally if I was to work musically in the directions implied by the video I would do that in software with supporting Excel calculations (like the video author) for precision and confidence in nonstandard tunings that complement a given timbre. I finding getting tuning and timbre stability in modular hard enough with conventional tunings; I can’t imagine trying to pull off what’s done in the video in modular. But of course that’s my view only.
Interesting stuff. Thanks for sharing! Good luck.
