Ok, perhaps some examples will help. See the attached files. You can copy the text and paste it into a text editor, then save it to a character folder with a cr2 file extension to test the file. First using linkParms to set a trackingScale. The trackingScale can be set to (almost) any value, incluting things like 0.00015, which is too fine to show on the dial but will still work. In this example the trackingScale has been set to 0.007. As mentioned in post #3, this file will NOT suffer from crosstalk! The actual morph channel 'targetGeom WideTop', has been hidden, but note that if the figure is resaved to a pallet it will show again in the saved version. To keep things simple I have knocked together a simple box figure with one morph 'WideTop'. Both the morph and the valueParm are in the square:1 actor. They are linked by a linkParms statement in the 'figure' section. The figure does not use ERC, at least not conventional ERC, though perhaps linkParms can be conciddered to be a type of ERC.
