[Andi]

the plugins you need are called RTAS (Real Time Audio Suite) plugins.
you can put those on your tracks, as many as your CPU will allow. Most
of them are available as AS (AudioSuite) plugins wich are rendered
effects.

Most of them are a bit pricey compared to VST counterparts and every
big plug-in manufacturer will have plugins in the RTAS-AS Flavour.
There are a few free plugins if you search after them.

You can find most of them via the digidesign website
