+There's a complication to this story, however. You cannot use MIDI
+learn with the GUI provided by the plugin. This is true no matter what
+the plugin format or platform is. When we refer to "whatever on-screen
+fader ..." above, we are referring to an “Ardour-owned” control of
+some sort. You can get access to that in one of 3 ways:
+
+<ul>
+  <li>right click on the processor element in the mixer strip, and choose “Edit with Generic GUI”</li>
+  <li>right click on the processor element in the mixer strip, and from “Controls”, make the desired parameter visible inline in the mixer strip</li>
+  <li>in the editor, click on the “A” (automation) button for the
+  track, find the desired parameter. This will make the automation
+  lane for that parameter visible, and it comes with a fader you can
+    use for MIDI learn.</li>
+</ul>
+
+You can’t just “click the GUI” because the plugin owns the GUI, and
+cannot (and should not) be a part of the MIDI learn process.
