Question Can I use PowerCore in my DirectX application like Sonar 4 (and below) or Project 5

PowerCore does not support the DirectX plug-in standard, as they are as VST plug-ins. Third party VST to DirectX wrapper solutions like the ones bundled with Sonar 4 (and below) and Project 5 allow you to host VST plug-ins with a DirectX compatible host program. However, we cannot guarantee performance or compatibility with VST-to-DirectX wrappers / adapters, nor are we able to support this type of setup.  For guaranteed performance, use PowerCore in a VST compatible host application. In the case of Sonar, we recommend you update to Sonar 5 (or higher), which adds native VST support.
