x-ray on vst3 plugins

X-Ray should work with VST3 plug-ins. Waves plug-ins may be excluded in the XRayExclude.ini in your user directory, C:\Users\yourUsername\AppData\Roaming\Cakewalk\yourVersionOfSonar. Don't know if Waves work with X-Ray now or not, they use to have problems with it, I don't own any.

Unless something change recently, Waves plug-ins cannot use X-Ray. This is way the line
XRayVendorExclude1=Waves
is in the XRayExclude.ini
