Hello,
Today I installed FXpansion's new Geist plugin and noticed some strange behavior when used in conjunction with the Virus. Namely, if I have VC loaded into an Ableton project, it knocks Geist out of sync when I try to record additional parts. In other words, Geist has an internal sequencer, and when I arm the record button in Ableton to access Geist's sequencer, it plays out of sync if the Virus is loaded within the project. I'm not sure if it's always been like this (I never really experimented with plugs that have their own sequencers before), but can confirm the same behavior with Stylus RMX.
This is really frustrating and after 4 (almost 5) consistent years of various sync problems I am at the end of my rope (which sucks because the Virus is my favorite sounding digital synth and I like the layout of VC).
