In QMidiRoute, if a .qmr file is loaded in which a saved Map used "Fixed" in the Output-Note dropdown list, the map behaves as though "Offset" was chosen, even though "Fixed" is displayed in the box.
If "Fixed" is reselected, the map then behaves as expected again.
I make a Map that takes any note and outputs a fixed note 4.
I save the settings to test.qmr
Later, I load test.qmr. The Map shows "Fixed" in the dropdown list, but the output is whatever note played plus 4.
I reselect "Fixed" from the list. The output is now always note 4 as expected.
