Running it on a PC.
It works... but barely. I can't run more than three or four instances at any given time, it will crash everything and I'll have to restart Reaper.
Also, if I close Reaper with an instance of Silver running, it'll crash the project... and I have to perform some necromancy to get the project open again, and then disable the plugin, just to even open it!
So in order to use Silver, this is my procedure:
1) Insert MIDI, insert Silver instance
2) Adjust MIDI so it sounds good
3) Render the MIDI into Audio
4) Listen to the entire track to make sure EWQLSO didn't have any rendering/sampling errors. Here's an example of a blooper I've had:

5) Delete the Silver instance.
Rinse and repeat. It's not so bad for one instrument... but when I'm working with a 15 voice symphonic piece its a NIGHTMARE. Really kills the creative impulse
But for some people it works perfectly. Not for me. There's no way to test-drive the software to make sure it works. And there's no way to sell it or return it if it doesn't. So... its just not worth the risk in my opinion. I'd rather spend a little more and get VSL. Especially since the VSL samples are dry, whereas the EW samples have a shitload of reverb.
