One complaint that I have with Komplete (including Ultimate) is that it doesn't include a decent parametric EQ. By decent I mean one that sounds great and has a usable interface.
If you just buy Komplete, you get these really outdated looking offerings, which are "custom EQ" (just tone, freq, scoop and volume controls), "Graphic EQ" (an 8-band graphic EQ with fixed bands that appears to me to be useless for anything serious), "Parametric EQ" (which only has 2 - count 'em - 2 bands and really clunky old style interface which is horrible for anything surgical), and "Shelving EQ" (yep, you get a high shelf and a low shelf). Not one of these has a hi-pass or lo-pass filter. Incredible, ain't it? And why they didn't just combine the shelf EQ with a parametric EQ, I'll never know. All pretty lame really.
If you buy Komplete Ultimate, you get the Solid Mix Series of plugs, which contains a very nice SSL-style EQ (switchable between E-type and G-type), and has 6 bands including a hi-pass and a lo-pass filter. It's basically very similar to the EQ that's in the mixing interface in NI's Drummer series and sounds great. However, not everyone is going to want to work with a non-graphical EQ like this (I myself like to see the curves). Here it is:
All in all I was very disappointed with the EQ offerings in Komplete Ultimate. Granted, I have other EQ's, but it would have been nice to be able to do all of my EQing in the Guitar Rig-hosted FX chains that I string together. It seems really strange that they're lacking in this area since all of the other effects are great. I really hope they offer something new EQ-wise in Komplete 9.
