I am a new Virus TI2 Darkstar Polar keyboard owner and bought mine brand new from Sweetwater. Great sounding synth with tons of power even in 2022 with all the fancy new gear from competitors. Some tips I learned
1. Mac OS users- find old computer with 8-16GB RAM and load older version of Mac OS X from USB boot drive. I like High Sierra and it works with the Virus TI software.
2. Join the Virus TI Facebook group
3. Be patient and have fun learning it. Very powerful complex synth with many sound crafting options.
4. Buy a good sequencer! I have a Squarp Hapax on the way.
