Whether completely obvious or under-rated, the QuadCurveEQ earned its stripes. Looking for a 3rd party, easily transferable replacement with the same feature set including larger display (flyout) with integrated FFT analyzer, note-mapping, Hi/Lo shelves, HPF/LPF, multiple curves including the resonance bump, etc. 
 
Best candidate in my limited search has been the FF Pro-Q. Expect Melda might have something useful. UAD/Waves are a no go for me. Not looking for cheap, but noting the asking price for these is right up there with complete DAWs. 
 
I'm sure I'm not the only one under a bit of a crunch to get things sorted out, any suggestions are appreciated. 

The Waves H-EQ is exactly what you want. I grabbed it for $29. It's very much like the quad curve, but instead of 4 emulations you get 6. It also has the built in analyser and HPF, LPF. IT's basically quad curve version 2.

The free melda EQ will do pretty much everything you’ve listed. If the screen seems to small at first just make it larger. Its resizable so you can make it whatever soze you want. Check out a vid I did covering it a while ago.

I thought melda freebies were size locked

Yes, without a license the MFreeFXBundle plug-ins may not be resized. The license goes on sale regularly. I believe the sale price is around $29.

Sure you have considered this, just worth remembering that Quad Curve will work outside of Sonar while you look for a suitable replacement.

I think you might be confusing QuadCurve with LP EQ.

Yes, sorry... Too busy looking at VST EQ options.
 
For Pro Channel replacements I'm looking at what is available in Cubase's Channel Strip, it has a 4 band EQ, along with Channel Modules like:
 
http://www.ikmultimedia.com/products/trwhitechannel/ 
 
http://www.ikmultimedia.com/products/trbritchannel/ 
 
Both have 4 channel EQ but lack the nice graphical interface.
 
For a more Graphical approach EQual looks interesting but I have not tried it out yet so can't comment on the ease of use or sound:

Channel Strip looks good but is not really a direct replacement for Pro Channel. I guess the reality here is that its a bit like switching from one high end mixing console to another, they are different. Where Pro Channel really scores is the number of extras available. Don't know if the Cubase Channel Strip supports 3rd party addons but if it does I'd love to see some of the Cakewalk and Third Party modules made available.
 
I guess one the dust settles extracting the content as products could be an option for someone using the Cakewalk code base.
 
BTW appreciate that this reads a bit like an advert for T-Racks. Reason for this is that I did the upgrade to 5 so I'm looking at getting the most of this investment in the current situation.

dmg eq's are nice, i use equick mostly https://dmgaudio.com/equick

@Chandler - Thx for the YT on Melda. I've used a few of their plugs but never taken the time to fully explore them. Nice job on the overview. 
 
@ampfixer - Managed to resist all the shiny Waves stuff so far, but will have to reconsider. Looks like a pretty good match. The L2 has been recommended as well.
 
@pwalpwal - Good one, not on my radar, thx.
