Action for selecting only the note under mouse cursor ?

[vanhaze]

I guess, i must be overseeing something very obvious but i just can't find an Action that does this:

In Midi Editor, when i hover my mouse over a note, the searched for Action selects that note, and only that note.
Not other notes above or beneath the pointed note, just that one note where the mouse pointer is on.

Many thanks for your help !

But doesn't seem to work for me ..

- I imported the script into Action List / midi editor context.
- I assigned a keyboard shortcut to it.
- I made a simple midi item in Midi Editor.
- now i place my mouse cursor on one note and hit the keyboard shortcut.
Outcome:
1) Already selected notes become deselected, but the note on which the mouse cursor is, isn't selected.
2) When no notes were selected beforehand, nothing happens when your script is executed,the note on which the mouse cursor is, isn't selected.

OSX 10.12.1
Reaper 5.30pre3.

This version should work (at least it does here):

local r = reaper; local function nothing() end; local function bla() r.defer(nothing) end

take = r.MIDIEditor_GetTake(r.MIDIEditor_GetActive())
if not take then bla() return end
notes = r.MIDI_CountEvts(take)
window, segment, details = r.BR_GetMouseCursorContext()
_, _, noteRow = r.BR_GetMouseCursorContext_MIDI() -- see http://forum.cockos.com/showpost.php?p=1749178&postcount=13
if noteRow == -1 then bla() return end

mouse_time = r.BR_GetMouseCursorContext_Position()
mouse_ppq_pos = r.MIDI_GetPPQPosFromProjTime(take, mouse_time)

r.Undo_BeginBlock() r.PreventUIRefresh(1)

for i = 0, notes - 1 do
  _, sel, muted, start_note, end_note, chan, pitch, vel = r.MIDI_GetNote(take, i)
  if start_note < mouse_ppq_pos and end_note > mouse_ppq_pos and noteRow == pitch then
    if sel == false then
      r.MIDI_SetNote(take, i, 1, muted, start_note, end_note, chan, pitch, vel)
    elseif sel == true then
      r.MIDI_SetNote(take, i, 0, muted, start_note, end_note, chan, pitch, vel)
    end
  end
end

r.PreventUIRefresh(-1) r.Undo_EndBlock('Select only note under mouse', 2)
