One of the bugs I fixed had to do with a parameter called "Tap Slope". It's busted in the PCM96 (as strongly attested by zmix) and it's fixed in the plug. It does cause a small difference in sound, and I will fix it in the 96 when I've got time.

There were a number of small changes I made in the way reverb decay time is measured. This means that there will be tiny differences in the time between the plug and the box--especially at small room sizes. One thing I've learned is that mixers use their ears anyway and not the numbers. It's easy to tweak from the fader, which is why it's always in the soft row. I'll backfill those changes in the box too, when I've got a chance.

There are a number of other little tweaks, noticeable or not, that are in my notes. So I'm not slavish about duplicating old stuff--warts and all. They are still the same algorithms--with corrections. They are in no way crippled.

And finally, I've been spending time 'recalibrating' presets. In general, you want something like unity gain through a preset. In truth, you can't get there, since the response of a reverb is so strongly dependent on the source material. But I'm still tweaking gains.

So even if you turn off spin, you'll find that algorithms don't null. Should they?

I've just begun a week of badly-needed vacation. I'll monitor this list while I can, but responses will be infrequent. I'm not ignoring you for good--just for a while.

N.S.
I couldn't find Nobody Special talking about C++ (I think it was Sean), but this is interesting nonetheless.
