If you use any of these, I'd recommend using DSK Choirs, DSK Virtuoso, DSK Overture, DSK Brass and DSK Strings.
For Philharmonic, I recommend just taking the instruments and moving them over to sampletank for use. I find it's better that way.
Generally, when using Kore 2, I recommend looking for sample-based instuments to use. The dubplate piano and suspense strings are pretty good.
Kontact 4 comes with a very good vienna cello. Also comes with an annoying 30 minute time limit. It can be reloaded though, as long as you don't save the program itself (I made this mistake, and now I'm going to have to record every single cello sample individually. That will literally take a whole day, but then I'll be able to make a soundfont out of it.)
Haven't tried this yet. About to try it now. I seem to have gotten stuck on the installer, but I'm going to keep trying though.
Because Sorohanro is a God.
http://google.com because I found more stuff via google than you can imagine. If you know what you're looking for, chances are that you're going to find it. You can also use it to look for forum discussions where they're discussing plugins, and find stuff that way.
And last but not least, my sig.
BTW, you don't everything listed here, you only need enough samples to complete an orchestra. Be careful which samples and soundfonts you use, and I provide this many so you can find the exact articulations and quality you want for your specific piece.
And I was going to post one more link to a 36 gig soundfont collection torrent file, but after looking through the file, I discovered that some are actually commercial soundfonts, so I'm not touching that.
