Ok, first off, why on earth would McDsp show a VST3 icon if they didn’t support VST3?
Every one of those links I just shared with you shows VST3 support. I also downloaded a demo. Guess what? VST3!
So they’ve run into some grief or other trying to support this platform; they said back in January, it would be there… 2 months later, and seems it wasn’t worth it. Like it was for U-he and probably many others, the VST3 debacle continues.
Try not to take this the wrong way. I understand you want the VST3 versions, and they really do exist! BUT… to form that statement that I just quoted above ^^^ is a far reach from truth because you had no facts. i.e.: You assumed there wasn’t vst3 support because KVR didn’t share it. You are a bad bad boy!! 
Stare at the cow! 
So, have joy! I used to use these plugins all the time in PT. I’m glad to see them come back to life and come to vst. My favorite is/was the ae400 active EQ.
