thanks for all the info here!

I have been using the remote control features of the Console View
in CakeWalk to move the sliders in the console for MIDI volume
control.
Right-click on the fader, select remote control
select Controller 0, MIDI chan 0...16 (slider 1 on the 168 sends
Controller 0 Chan 0 by default - at least on mine)
This only works reliably in 8.04

This way it is fairly easy for a new project to set up.

Not being very knowledgeable about MIDI controller messages: is
there a conflict to be expected from using controller 0 this way?

Best,
Wolfgang
