I now understand what you meant. I was looking in the main menu, not the notation editor window. I now see that "user setting" refers to a specific type of pitch bend, not simply a pitch bend value. I like that the Controllers-> Set function accepts the 4 digit numbers of MIDI pitchbend units that go from 0 to 16383, but I have already become accustomed to converting that value to MSB/LSB notation because that is what the Event Editor accepts.
My preferred workflow is to place my notes in the notation editor, then switch to the event editor and insert a pitchbend event for every note. I type in the msb/lsb such as 64,0 for no pitch bend or 50,36, etc. I keep a text file of notes with the msb/lsb for each adjusted note separate for every tuning I work in (13 notes per octave, 17 notes per octave, etc.).For me doing it en masse is not as useful since I am shaping the melody and song as I go along. I do not know in advance exactly what notes I want where. Thanks nonetheless, because I learned more about Rosegarden in the process!
