Setting up Virus in Logic

[Nicko35]

I have realy big problems vith setting up my Virus Ti2 in logic,as i understand it should be possible to use three sounds at the same time by using multitimbral.
And fine that works but i can't solo or mix the seperal sounds in the mixer.
Vhen i mute let's say the först track/sound in logic i mute all three sounds that i'm using.
Can someone please help me?
I have tried this tutorial but i just can't get it right,si there a better way than using multitimbral?
