Hello GarLander,
it is possible on PC. However not all hosts can handle this properly.
1) Close your host
2) Install Saurus1
3) Rename Saurus.dll to Saurus1.dll
4) Install Saurus2
5) In case you want to load the old version load Saurus1
I did take big attention on Saurus2 that the sound really only enhances compared to Saurus1. Mixes created with Saurus1 should work very well and have an enhanced sound if you load them with Saurus2. That's why i recommend to have Saurus2 installed only.
