Isn't that like the Ursa Major Stargate 323 Reverb? Greybox audio released code for this about a year ago: https://github.com/greyboxaudio/SG-323

Thanks for mentioning this project, I have been looking for a good reverb plugin for Linux for a while now and this sounds great.

		There might be a plugin based on freeverb, which is also a good sounding one. I ohave it as a logue unit, so can't recommend one immediately. At least I know greybox based on actual device comparison, as he owns one and has been doing this for 5 years sans AI.
