These controller names and numbers are the standard MIDI controllers. They do not necessarily work on plugin parameters, even if you find the same names there. > I tried to programm the controller by using control > surfaces>control assignment>learn assignment.

Select the track where your plugin sits. Open the plugin window. Now open the Controller Assignments and enable the "Learn" button. Move the element in the plugin window with your mouse, then move a knob or fader on the keyboard. Disable the learn button. That way you tell Logic which parameter of which plugin it should react to which knob. Always on the selected channel. At least I do not know if the other option, the object number, works properly. If the plugin does not react or behaves in a weird way, there is nothing you can do but delete the learned parameter. Logic Express is very limited in that area. > What are the Logic's CC numbers for those parameters?

You find some controller numbers in the plugin reference manual. You can insert a plugin with known controllers in the selected channel, program one knob on the keyboard and look if the desired parameter reacts. If not, you can go to "File >> Song Settings >> MIDI" and change the last dropdown menu to "Version 4.x Behavior". If that doesn't work either - end of my wisdom. As I said, Logic Express has very limited control capabilities. I works with a "supported suface" but not very well with other hardware. ___ Peter Ostry
