Here's another one, it's a clone of the Ursa Major SST-282. I've based the design on the patents, user manual and service manual, but tuned it myself, and again added some enhancements. I'm not emulating the glitchy, non-interpolated delay modulation and I'm not including the selection of "rooms" (I don't have any information on the delay times here, and they don't seem extremely useful anyway). It's a very idiosyncratic algorithm, and certainly not an all-purpose thing since it turns into weird slush for long decay times (it actually has to, to prevent unstable feedback).
With some modification, it could work well as an initial stage for a more advanced reverberator. You can get away with a large amount of "feed forward" modulation, and the sound can be made extremely rich if it's then passed through some APF diffusion stages, or FDN or whatever. If a signal recirculates through a modulated delay (as in the reverbCH algorithm I posted earlier), it becomes increasingly detuned over time, so this limits the maximum modulation amount versus decay time. So if the goal is to be "lush" sounding, it's possibly better to keep modulated delays out of the main recirculating part.
I've got a selection of original algorithms too, but they're continual works in progress, and much more computationally expensive...
