It is a lot like QuadCurve but (IMO) better.
1. You can insert multiple instances (e.g. pre/post compression)
2. Every single parameter is very simply automatable
3. There's a mid/side mode, plus you can EQ left and right (or mid and side) separately
4. You can create bands where needed up to a maximum of 24 (!)
5. It has a linear phase mode, so it doubles as a mastering EQ
6. The frequency analyzer is way more customizable (set resolution and speed, and you can show pre and post at the same time)
You wouldn't regret adding it to your setup. It's my go-to EQ for most stuff now, but as you know, I was trying to get away from PC, and I know you're not.
