DSF replied, plainly suggesting I review the default installation paths. Following this, I uninstalled Sonar X3 and the Examples Pack, then clearing the registry of every trace of Cakewalk Whatever I could find.
NEXT...I re-installed Sonar X3 32, 64 and MC6T, then the DSF Examples Pack. The Examples STILL don't appear in SoundCenter. (Oh, they're in the right path and I could try copying them to my existing VST folder, but last time I did that, things only got worse.) On a separate note, the install is creating Project folders all over my hard drive and that drives me bonkers.
I'm so frustrated. Instead of working on music, I'm spending hours reinstalling my software repeatedly to troubleshoot this ridiculous issue. Of course, I don't need more instruments, but that's not the point. The point is that no extra Sound Center instruments are being detected...
ever.
I responded to DSF instantaneously and I'm going to post this issue in the
Cakewalk Instruments Forum.
Pending this, I may just reformat my hard drive and start from scratch.
