Bub, what you're discribing is not "The Pro Channel", it's the track inspector window.
Yes, you are right. The Track Inspector houses the Pro Channel.
I'm just thinking about this whole scenario again because for the first time since I've been using X2/X2a, and I've been using it heavily the last couple months, I had a module become unresponsive in a project like I was plagued with in X1. It was the FX Chain Module. I had an EQ in there with a steep cut to the low end on a guitar. I was A/B'ing it with the On/Off button of the FX Chain Module and it suddenly stopped responding and it was stuck on even when I had it off. I ended up having to save the EQ settings in a preset inside the VST, remove the FX Chain Module, and reinsert it.
But I really can't complain ... it's the first time it happened to me since I've gone to X2. Considering what I went through with X1 ... it's ok. But man, I wish I knew what causes this.
