MC Mix plug-in control problems

[benderissimo]

I've just started using a pair of MC Mix surfaces and have found that quite a few of my plug-ins simply don't map correctly to the rotary encoders. All of the controls in the Steven Slate plug-ins snap to zero when you touch the encoder and don't move as you turn it and in Sound Toys Decapitator the LPF control only seems to work between minimum and about 1.6kHz (although all the other controls work as they should).

So far these are the ones that don't seem to work properly:

Steven Slate VCC
Steven Slate VTM
Steven Slate FG-X
Sound Toys Decapitator.

Anyone else have these kinds of problems.

I'm running Pro Tools 10.3.2 on OSX 10.7.4 with Eucon 2.6.2. The surfaces both have the latest firmware installed (1.5.1) and the plug-ins are all the latest versions.
