Dietz, I'm wondering if IEM or VSL have somehow managed to pop a welcome little bit of modulation into MIR 3D's convolution reverb?
I don't own old MIR but in many of the older mockups posted here I used to notice the 'crystalline rigidity' of convolution reverb a lot. This inherent characteristic of convolution reverb sounds distinctly unnatural because in any large auditorium filled with an audience (each person producing around 100W of body heat), the air is never ever perfectly still. Hence in reality the resulting reverberant ambience always has some dynamic aspects. One of the advantages of algorithmic reverb is that modulation can be added and adjusted to taste. This is why it's often beneficial to add some modulated algorithmic reverb to 'sweeten' a mix that relies heavily on convolution reverb.
It's hard to be sure but as yet, using Synchron instruments (tree mics only), the crystalline aspect of new MIR's convolution reverb doesn't seem to be quite as apparent as what I've heard from old MIR mixes. And I haven't yet used any added algoverb in these tests. If there is no deliberately added modulation in new MIR's convolution verb, maybe it's just my post-purchase positive prejudice affecting my hearing. Or ... could it be that Synchron Stage A's natural reverb is lending just enough motion to 'liquify' and stir up the resulting convolution somewhat in new MIR?
Of course I'll understand a reply to the effect - "VSL can neither confirm nor deny that modulation has been added to MIR Pro 3D convolution reverb." lol. Trade secrets are trade secrets!
In any case, when I have some time, with some of my VI instruments I'll be experimenting with small amounts of modulated algoverb (no more than scoring stage size) inserted prior to new MIR, to see what happens.
