Dave Smith Instruments SYNTHESIZERS

Hello people 
I just joined so i'm very exited to share our experience together
sorry for my english i'm french...

Here's my first topic>

I own two evolver (Desktop)and would like to know if the SoundTower
editor Works well as a VST and if it can control my evolvers separately?
I usually use Ableton Live So please let me know if I can automate my
evolvers Just by creating two editors in two differents tracks(and I
dont need to buy it to times!).

If not wich editor do you advise?

P.S If anybody found out about the freeware "that can be found for PC"
Let me know thank

If anybody wanna share his editor you got my email! ;-)
