I'm currently experiencing a strange problem with my CbB installation.
Yesterday I got rid of my old MIDI keyboard, and replaced it with a Nektar Impact LX88+. To use all the fancy bells and whistles of the new keyboard, I installed the Cakewalk integration package from Nektar. That's when all hell broke loose.
Immediately after adding the control surface, I got a message box saying that no audio device was available. In the preferences dialog, I could see that my audio interface (Roland Quad-Capture) had mysteriously disappeared from the list of available devices. First I tried to simply restart CbB, but that did not fix anything.
Then I uninstalled and reinstalled the Quad-Capture device driver, and also upgraded CbB to the newest version. The list of available devices would now be filled up with cryptic entries that made no sense to me. However, the Quad-Capture was also listed, but every time I tried to select it and click Apply, I would get an error message about the current audio format not being supported on any device. However, after a couple of reboots and a bit of experimenting with the settings, things suddenly seemed to be back to normal again.
But much to my disappointment, as soon as I tried to open a project, CbB would terminate. This happens consistently whenever I try to open an existing project or create a new one - even if it's empty. CbB will perform the usual actions as indicated by the popups in the lower right corner, but just when it's ready to update the GUI, the application dies. No error message or anything - it just disappears. This is obviously a bit of a showstopper, so I really need to find out what's going on.
I also observe that the Quad-Capture will repeatedly disappear from the list of available devices. Rebooting the computer fixes this, but it's still annoying.
Any suggestions on where to begin the troubleshooting?
