Thanks for the reply.
32-bit plugins need to use 'bridging software' to be able to run in 64-bit Sonar. Sonar comes with something called BitBridge, which attempts to allow 32-bit VST plugins to run in 64-bit Sonar.
It doesn't always work, and MANY problems have been reported with 32-bit plugins causing crashed and also really wacky behavior when used in 64-bit Sonar. That was why I had asked.
Another similar piece of 3rd-party bridging software is available - called JBridge, and for some 32-bit plugins, it worked better than BitBridge, at allowing them to run in 64-bit Sonar, but here to, MANY problems were reported with both crashes and weird behavior.
Soooo, generally speaking, it is the general consensus that if running 64-bit Sonar, then trying to eliminate all possible 32-bit plugin use is best. Many of the more supported plugin vendors have released free 64-bit versions of many 32-bit plugins, so you might wish to check that for any that you really want to try to hang on to.
With regard to your thought that Sonar should be able to intercept and report on plugin failures, this is not always possible, as control can get turned over to the plugin for processing, and then it is the responsibility of the plugin to handle any exceptions - including reporting on them. (as far as I know).
If you call Cakewalk Technical Support, and provide them with the report number for what you sent them, they may be able to give you more information to go on - which may include either a workaround, or they may have been in contact with East West folks and could possibly pass on information as to what happened and when something might be available to stop it from happening in the future.
Best of luck with the situation - I HOPE to be able to pick up some East West strings version, and am looking forward to getting access to better sounding solo violin sounds. :)
