Windows XP, 1.8 clock, 1 Gb Ram, 7200 rpm hard drive, Sonar 2.2 with Cakewalk VST adapter. Sound card is Audigy 2 ZS. All drivers everywhere up to date. Free of spyware, virus, etc. Norton Utilities show no problems. PC Dr also checks good. Locking out swap not selected. Don't use DFD.
When using the VST adapter, Sonar crashes so often and lound sounds like thunder rolling over the redwoods.
I removed Sonar, GPO, deleted folders, cleared registry entries. Re-installed all fresh. No change except more hair gets torn out of my nearly nude scalp!
I can open VST from the Synth Rack view. But from that point on, chance reigns supreme.
According to Dr Watson, the crash is due to access violation, but that helps me about as much as a butter knife would have helped St. George with that dragon.
Using DXi has not caused problems. Maybe I should just go that route. However, I am hard headed, perhaps because I just bought the VST Adapter from Cakewalk. Previously, I had used GPO Studio as my vst host for Sonar as well as Sibelius, but most often with Sonar. In either case, no problems, except that as I expand number of instruments, CPU usage increases quite noticeably.
Cakewalk might eventually solve the problem, but even allowing for the longevity of my family, I have not more than 30 years left for waiting time.
