I would also add that I would like to be able to remove the quadcurve from the channel if I'm not using it.

I would like that as well, at least you can collapse it though.

Like any fx, we should be able to use multiple Pro Channel modules in any sequence we want.

Yeah, this just came up for me, exactly as mentioned above, wanting a quadcurve before AND after a compressor.  As I sat looking at ways to solve it and what EQ I would choose, I suddenly got confused about why there are two paradigms - an effects stack in the primary channel strip and then the add-on prochannel that you have to pop before or after the effect stack.  Then we have the work-around thing with the FX Chain, to let us weave non-prochannel plugs into the prochannel.  I am starting to feel like it really is a user interface design mess.
 
In any case, I agree that we should be able to have more than one quadcurve in the PC.  I guess what I really wish for is a single container, perhaps designed visually like the prochannel, that could host any of the PC plugs as well "non-prochannel" plugs, without having to hide the non-PC plugs in a container.

All restrictions on the Pro Channel should be removed. Not only to use any number of instances of quad-EQ (including none). Also, the default bus and channel compressors exclude each other and are limited to a single instance. Tube saturaton is also limited to a single instance.
 
I don't think there are any technical reasons for these limitations. It's just the idea of the Pro channel rebuilding a real console, where this kind of limitations would hold.

Multiple instances of PC EQ and/or at least a second striped down version for low/high cut or shelving.
 

actually I would really welcome if it was possible to "pin" the expanded view of the EQ, and be able to MOVE it around, so that way I could open multiple track EQs :)

The ability to stack multiple ProChannel compressors would be nice, too!

It is possible except for the PC76 U-type and PC4K S-type bus compressor. They were written before the modular PC when there was only one slot for a compressor. All the other PC compressors do not have the original PC restrictions.

Sorry, scook, that's what I meant - multiple instances of the stock 76 and/or 4K compressors.

Strange is that starting a blank project and adding a track will result in a totally empty PC. No QuadCurve, nothing.
 
So a PC without the QC EQ is technically possible.
 
But if you then add the QuadCurve, you cannot ever remove it again.
