Hi-where's a good place to start with this stuff?

i just started using a small VST verb thru "mini-host'
on a P3-800-PC.I can dedicate this PC for just reverb.
Running Gigastudio into it & out-works fine.

Whats a good plug-in to start with-and where are the impulse files[wav i guess??]


...oh-what is SIR?

-found it-looks fun!
