Hello,
we are starting to deliver the licenses right now!
We have received thousands of requests and we are processing them in chronological order.
Please note that REmatrix Solo will be delivered as a REmatrix Library.
In fact the Cakewalk REmatrix Solo was a ProChannel module, which is a Cakewalk proprietary format, so it cannot be opened into other DAWs "as is".
So, we decided to pack the REmatrix Solo content (i.e. all the IRs and presets) into a REmatrix library that you can use within the free REmatrix Player. REmatrix Player, by the way, is a richer version if compared to REmatrix Solo.
The installation instructions are provided in the email messages we are sending now.
