I redid the test again now that I have a better understanding of the problem. On the MC using the touch mode the witting does not stop instantly when you release the fader.
But touch mode and touch sensitivity may not be the same thing I would think. That is touch mode may not be using the touch of a surface but the end of movement to determine when the automation is to stop. It should what ever mode its in but I don't think CW has Sonar set up for that. It is true that there are more touch sensitive CSs around now but far more CSs without it still. None the less all of us that do have it should be supported.
Right now I'm not sure what is going on or what to expect. I do know that the Logic Control had all these modes with Logic. But I can't recall what each mode did differently and how.
You may have brought an issue to the forefront that needs further explanation.
In the case of the Mackie Control the copyright is 2002-2006. Which means to me no updates have been made for a long to it.
Also keeping on the subject touch in the dialog we have an option to touch the fader and thus select a channel. This obviously has nothing to do "touch mode".
Really the MC is being wasted under X2. It should work with the ProChannel but it doesn't.
