When there is EP in a lot of actors, the following method may prove quicker than deleting the master channels by hand. You will need to use a text editor (or cr2 editor) that can search and replace multiple lines of text. I use EditPad Lite.

In a normal EP set up there will be 11 different internal names used for the master channels. In Ajax's EP Tube these names are:

 QT1UTwistAll
 QT1UTwistAfter
 QT1USSideAfter
 QT1UBendAfter
 QT1UTwistBefore
 QT1USSideBefore
 QT1UBendBefore
 QT1UWave1S
 QT1UWave1B
 QT1UWave2S
 QT1UWave2B
(note there is a leading space before the names)

Use your editors Search&Replace function to replace each of the above strings (might be different names in your cr2) with the string " ???" (note the leading space). Next use the whole of one of the "valueParm ???" channels (it may be a targetGeom channel in some implementations) as a search string, and leave the replace string blank. This should remove all of the EP master channels. Then proceed as in my previous post to load and resave the figure in order to remove the slaving code.
