We're part of a trial to help Cakewalk evaluate all the new systems that come into play in the purchase, download, installation and registration process. Cakewalk have invested a considerable amount in all these system and rightly is testing them out.
As well, once we have the program installed successfuly we get to use it and help promote it on the forum, which is working out well as its been a very stable and mature release.
I don't think there's any hidden agenda, in fact when talking with the cakewalkers through the forum there's this joy that comes through what they say because this is not just a new program release it's a new Cakewalk all round as far as I'm concerned.
