Thanks, will check this out! Does the modulation only work to blend between two different IR or can it modulate other aspects of the sound? Will of course demo myself as well.
Reverberate has some interesting options. There are two IR slots that can be modulated between, but there is also the notion of "fusion IRs," which are single IRs containing multiple variations that modulate within themselves, kinda like a multisampled impulse. You can put one of these in each IR slot, and modulate between them.
Then, each IR has a chorus, delay, and EQ. The EQ can be set to change over the length of each impulse, which can create a dampening effect like you'd find in an algorithmic reverb. The chorus is post IR, but there's a "splitmod" for each slot as well which can modulate pitch for the ER and tail sections independently.
You can have each IR and its chain in series or parallel, followed by additional master chorus, delay, and EQ modules at the end of the chain.
Each IR also has start position, length, ADSHR, width, predelay, pan, and gain controls, the combination of which allow you to do some pretty tremendous shaping.
And, finally, you can also opt to put an algorithmic ER or tail generator in either of the slots instead, with a decent assortment of parameters to fiddle with.
If nothing else, they give you choices!
