Question

You can Tab through the transients using "TAB" which is great.

Why not have an "Insert Bend Marker" Button on the Audio Bend Panel
if there's a button to remove them - for the sake of logic.

There would be enough space on the panel...

Answer 1

There's an "Insert Bend Marker" keyboard command that is assignable to a keyboard shortcut. There's an "Insert Bend Marker" command that is in the Macro Editor window that is Macro assignable.

Does that take care of it? This seems pretty covered for all use cases! :)
