All of this is more complicated than it appears on the surface. For example, I don't think digital performer is keeping Motu alive. I think it's the interfaces. Pro Tools, Cubase, Studio One, Ableton, Logic all have hardware components. You can't download hardware from a torrent! Software theft is still a huge problem, and a software-only company like Cakewalk has a really tough climb ahead of it. If everyone who used Sonar had paid for it, the situation could be very different. Also bear in mind that it has to compete with Logic, backed by a company with 88 billion dollars in the bank or more, Audacity which is free, and Reaper, which was bankrolled by someone who made half a billion dollars selling a program to AOL.
Consider Studio One. It's worth it for PreSonus to have developed it if for no other reason so that it didn't have to pay license fees to another company to include software in their interfaces. The fact that it has taken off on its own is welcome for them, of course, but that's in addition to other valid reasons why it should exist.
I truly believe Gibson wanted to make Cakewalk succeed where others had failed. Unfortunately despite years of trying, it just didn't happen. I think there was some hope that something would pull it out at the last minute, like momentum. The person behind momentum was convinced it would be a huge success, but when it was introduced, it did not garner much interest and certainly did not garner much income...certainly not enough to justify keeping the company going. It's definitely a sad turn of events, but I can tell you that Gibson did want Cakewalk to be successful, it just couldn't make it happen any more then Roland could.
I do think that the announcement from Gibson should have been more specific about what will happen with the community, and the current owners. However the transition team at Cakewalk is going to be tying up loose ends, and don't forget that Cakewalk has always been a very customer-centric company. I think they're going to do everything they can to make sure existing customers can use the software for as long as possible so that people have time to transition to something else if that's the path that they need to take, or to see if by some chance something does happen with Cakewalk.
We will see what the future brings. Remember that the music industry is a fashion industry and everything can change in a matter of moments. Sometimes that works against you, as it has in this case. But, sometimes that works in your favor. If I could see the future, I would be buying and selling stocks, not writing books, doing seminars, and consulting.
In retrospect, there were probably things that could have been done to save Cakewalk. But while Sonar had an undo function, life does not, and that's why we are where we are...
