I believe Sonar X2 was the last version to include V-Vocal.
This is correct. It was also the last version to include VC-64. V-Vocal is unusual in that it is part of the core SONAR install. Instead of being listed separate in the advance install component list, it is part of a minimal installation only. Probably because it was not treated as a regular plug-in by the program. Here is what the advanced install for V-Vocal looks like in X2
VC-64 is further down the list of Audio Plugins shown in the image and may be installed by itself using the advanced install option in X2 or older.
