So having this same issue
My Nektar expression pedal works fine in Amplitube....but still not being seen in Cakewalk for the Amplitube plug in
On the Amplitube plugin contrul panel, under teh VST3 menu....I do have "Enable MIDI input" checked
But on any wah pedal....when I try and go to the learn function for the pedal, its still greyed out
Missing a setting on Amplitube or Cakewalk you think ?
Attached are the relevant screenshots
On the controller panel as well everything locked....wont allow any changes either if that matters (screen 3)
