It is not like you can install just those plugins- you would have to install the whole X2 or X3 which are at least 1 Gb of space.
I was about to post this question- hope I can ask it here. What would I loose if I uninstall X2? Do you mean these (X2 - Analyst, FX2 AmpSim, FX2 Tape Sim, R-Mix, VC-64 and V-Vocal) will be gone? I dont know what Analyst or FX2 AmpSim, FX2 Tape Sim, R-Mix, VC-64, but I use V-Vocal and would like to keep it. Thank you.
