Hi,
In another thread, I mentioned the GOYO Voice Separator plugin that can remove vocals, or at least reduce them way down, without greatly affecting the other audio. It has 3 tools - Ambience, Voice and Voice Reverb - so it acts like a Noise Reduction and DeVerb (remove reverb) tool. It seems to be very good and I am impressed. It is currently free as it's a beta until the end of October. Anyone signing up will get a big discount when the final version comes out. The installer installed VST2 and VST3 dll's so it can be used in Movie Studio Platinum/Suite (in the Mixer) and VPX15.
Here is a sample without plugin, then with Voice Removal at -30dB, then with only Ambient Noise Reduction at -10dB:
