Hi Dietz!
I didn't know about Todd AO but if I mentionned them it was to avoid mentionning Altiverb.
I have always and ever been a big VSL Fan. MIR was for me a great tool for one of my project. But a felow composer once showed me how to setup Altiverb and I had to admit the color (using Todd AO) was (is) much better.
The first thing I did when MIR PRO came out was to try different settings (mics, EQ) to get a great color but it was not as good...I'm sorry to say so...
Despite this, I'd like the people reading this to know that MIR is great...no INCREDIBLE! The tool is now much better now being linked to VE pro using network. Soundwise it's much more a matter of taste than anything else!
