If you're a Reason user and interested in mixing for Dolby Atmos, this is THE solution. I can't recommend this enough. It can make any stereo only DAW (like Reason) capable of mixing Dolby Atmos and it makes it so simple.
Another thread I had started with the initial release of the full version and Essential: viewtopic.php?t=7531387
Essential was $149 and is now free. Definitely worth checking out even if you're only are curious about mixing for Dolby Atmos.
