virus c and logic 7

[mr.e]

Hi I bought a virus c yesterday again after selling mine about close to a year ago.
the whole plan was to save up cash for a ti but after reading about all the bugs and stuff I decided to buy back my virus c second hand for even less than what I sold it for so I gained 100 bucks or so.
I am a new mac user and would like to know about virus c and logic 7 setups.
how do i switch programs from within logic 7 ..I know I had it in logic 5
but i am not sure of 7.
Also I saw that cubase users get the advantage of using like a vst plugin to control their virus c synths....you can download at this site

I'de like to know if their is a logic 7 version of something like this that would be really cool!



another question I had was when my virus c is in single mode in logic 7 i play any sound and tweak the virus knobs and it works as expected but then when I switch to multi and multi single I play a sound and twist any virus knob and nothing happens....on the lcd it shows its tweaking but nothing happens. even when switching sounds it doesn't switch only when I use the logic midi library thingy
