Yeah, I’ll definitely be keeping an eye on that.
Have you tried Precedence/Breeze, BTW? That combo is working well for me so far, but doesn’t support smooth automation, so it’s not a good fit for sound design, foley and the like, where you might want sound sources and/or mics moving around. You can “fake” it to some extent by crossfading between multiple, carefully (due to phase issues) placed sources, but that only goes so far… Experimented a bit with that here, but ideally, I would have wanted the “walker” to actually move through the ambiences as well, but that would have resulted in a project the size of some people’s orchestral templates…
Haven’t researched the organs properly, but that would basically be Hauptwerk (sampling) vs Organteq (modeling), as all of these (short of a few really old ones) are for Hauptwerk. Technology aside, it seems that Hauptwerk is a much more mature and complete solution, and also appears to be aimed at real organists, actually serving as an alternative to real pipe organs. Whereas Organteq seems to have a fair bit of tweaking options for its one “builtin” organ, there is a substantial library of real instruments available for Hauptwerk, and they seem to be all deep-sampled individual stops. (Unlike most sample libraries, which only include a small selection of stops, or even just “baked” configurations, eliminating the whole “synth programming” aspect of actual pipe organs.)
