My understanding is that some additional support people have been hired (as have some more developers).
Again with the standard disclaimer that I don't speak for Cakewalk...I've had interactions with support at multiple companies. The reality is that support people have a limited shelf life for the gig; dealing with people who call up and yell at you tends to lose its appeal after a while. Of course not everyone is a jerk, but I see what the support people at Gibson go through and their patience is a wonder to behold.
So if multiple support people reach the end of their shelf life at the same time and bail ("I'm leaving, I got a much better job - catching rabid dogs"), you have to find replacements quickly. However then they have to be trained.
Paradoxically, I'm sure it doesn't help that Cakewalk is on a roll. The rate at which SONAR is gaining new customers is off the hook, and new customers tend to tax support much more than veterans who can state a specific question in the forums and get an answer a few posts later, or search the net and find an answer. Hopefully Cakewalk will be able to get any new support people up to speed expeditiously.
