I'm a little puzzled.

I have remixed some old tapes, making heavy use of the
Waves Native Power Pack plugins.

Everything sounds good, but what I want to do is rather
than send out through my spdf outs into a
DAT,
I just want to render the file inside the environment.

The track effects render fine, but the Waves stuff does
not. Is there another way to render the mix
down without going to another machine?
