I have run into a situation for which I must either:
1. Forget about using a VSTi that I'd like to use in Sonar X3 Producer under Windows 7 64-bit.
2. Uninstall SynthEdit, INCLUDING the safe removal of any registry keys it leaves behind, install the VSTi in question in Sonar, set Sonar to NOT scan VSTs and then reinstall SynthEdit.
I'd really prefer option 2, but again, I need to know how to safely remove those registry keys.
