SoundGrid version is on the way!
From the plugins main page - SoundGrid version coming in a few weeks... no cost upgrade for all owners.
The current version does not yet support the eMotion ST mixer, MultiRack, StudioRack, and SoundGrid processing. A version supporting all of the above will be released in the coming weeks and will be available as a free download to anyone who purchased the current version of the plugin.
