I personally couldn't care less about IK's abandonware (hee hee), but this new Neve emulation is pretty dang good. It sounds nearly identical to the UAD version. And its GUI is easier to deal with.
HOWEVER, there's the question of whether you need this plugin, given all the other high-quality options out there. IK is billing this as a great bus compressor, and it may be, but don't they already have a plugin called ... "BUS COMPRESSOR"? I think that one (an SSL emulation) is just as good as this Neve. Do you need both? I don't think I do. Not to mention all the excellent offerings from Slate, UAD, Waves, and other vendors. Help, plugin overload!
I won't even get into the whole "IK Way" of selling products. Suffice it to say that it had better be something I MUST HAVE for me to bother jumping through all their hoops. Not to mention that you can't even find the price of these things (in actual money) from their website. Who else does that? Answer: nobody.
One more thing, and I'll stop (I promise): those of you who like having the option of selling your plugins on the used market should know that these T-RackS singles bought through the Custom Shop are NOT FOR RESALE. You can't transfer them to anybody else, ever. Better make sure you use your oh-so-generous 3-day demo wisely, cuz if you buy it, you're stuck with it.
Good products obscured by loopy business practices. That's the thing with IK.
Cheers,
Eddie
