I read the whole thread about native Linux plugins, specifically looking for some that can just be dumped into the .vst folder and will work right off the bat, with no additional bridging, converting, or wrapping needed.
I found links to several things in that thread, but not specific cool plugs that do not need any additional help to get working, or require you to compile them yourself, so I thought I'd start that thread here.
Here's three native Linux 64 bit plugins I found last night that all seem pretty useful. Just uncompress them, drop them into your .vst folder, and they work with no additional steps.
Mverb - Pretty decent native Linux 64 bit verb
