Well, if the original poster is anywhere in this neighborhood, I would like to suggest that you (OP) post each issue you are experiencing as a separate thread, and give us forum folks a chance to help you get things resolved.
I would like to know what issues you are having with Boost11 - one common issue that comes up with it, and others, is that it is meant to be used AFTER a given project has finished recording - it is meant for use in mixing, due to its need for a much larger buffer.
Boost11 and Perfect Space, and plugins that either use a type of processing called 'look ahead processing', or chew up a lot of CPU and and do add large amounts of DPC Latency, and need the ASIO Buffer Size jacked way up in order to have enough 'room' to properly work without audio problems.
When I track/record, I run with an ASIO Buffer Size of either 128 or 64, but when I mix - I change my ASIO Buffer Size to 1024 or 2048, which gives the heavy duty plugins meant for the mixing stage enough buffer to process properly. MANY times, folks discover all of this the hard way - they either track without effects, OR swap out effects like Boost11 with others until they finish the recording of their tracks, and then after they move into mixing and reset the ASIO Buffer Size way up, THEN they will add plugins like Boost11, and then they don't have problems.
Another possibility had been pointed out way early in this thread, was that 32-bit third-party plugins can and do SOMETIMES cause stability issues, when loaded into projects that are running in a 64-bit Sonar. BitBridge and even JBridge do NOT always completely work for some plugins, and IF you see either Bitbridge or JBridge in memory, you DO have one or more 32-bit plugins loaded, and you may need to swap one or all of those out for 64-bit equivalents, OR work in a 32-bit Sonar for that project.
Anyways, lots of folks are getting lots of things done with Sonar, and there are a bunch of folks in these forums that will work with you to help you resolve issues you may be having - IF you engage in the forums by posting each issue in a separate thread. Hang in there with it :)
