At the moment we only have a two weeks trial of the Stereo version but, if interested in Multichannel, you can contact us at
https://helpdesk.dirac.se
(you'll need to "Sign up for an account")
We will manually enable a one month license of the Multichannel version (please make reference to this post/thread)
Also, a video with a walkthrough is available here,
