The 64-bit version of SONAR doesn't support 32-bit DirectX plugins which is what those are.
Here are some possible solutions:
- Use the 32-bit version of Platinum.
- Use the old version of SONAR that the plugins came with. I usually just end up doing this since I rarely dig into those old projects.
- Use a DX to VST bridge plugin that supports 32-bit DX plugins (not sure settings get automatically transferred in this case).
- Purchase the plugins from Timeworks who I believe made a 64-bit build available at some point (also not sure about settings transferring).
