Set MIDI note length in item from arrange window?

[Joe90]

Does anyone know of a way to to set all midi notes in selected items to grid length from the main arrange window?

It's an essential one for me, and I'm very surprised that I can't seem to figure out a way to do it... I'm hoping it's possible.

I've figured out my shortcuts for pitch and velocity without needing to load the midi editor, but not note length.

Cheers!

Option 1 :

There are "quantize note end to closest grid" scripts for main window. You need reapack installed.

Option 2 :

Use the inline midi editor for items. This way you don't need to open the Midi editor window.

Thanks for your quick reply! However I really need a way to set all notes to one length, rather than quantizing the ends - they are quite different functions.

Also, regarding the inline editor - once you're 'inside' the inline editor it has it's own set of shortcuts that can't be combined with the main ones, so I still can't set all the note lengths with one shortcut, which is what I really need, because I need to do be able to do it to multiple items at a time rather then clicking each one and opening individually, selecting all the notes - hitting the shortcut - then doing the same again for each item individually.

I'm aware I can open up multiple midi parts and edit them all together in one window, and I do have all the midi editing preference set up correctly so that it does this by default - I can select multiple midi parts, open the editor, Ctrl-A to select the notes in all the items, and move or resize them all together, but when I fire off the 'set selected notes to X velocity' script, it only effects the part that's focused, regardless of selection. Same with the 'set note lengths to grid size' command... which is strange.

If this method worked as expected for me then it wouldn't be such a big issue - as I could just select all the midi items I want, open them all together, select all and fire off the shortcut - still not as quick as doing it from the main window but not a big deal. However the current workaround of having to open each midi item individually is really not ideal, neither is gluing them, as they may be spread around in different places.

not sure if this helps but

either while in the Inline or MIDI Ed., select all notes and hit Cntrl+F2

enter the note length you want in the field and OK

the values can be a little funny but things like 1/2 or 1/4 work

Cheers for this Hopi, not specifically what I was after but still very helpful to know. Much appreciated.

Should swing be applied? If not, try this script:

-- BEWARE of creating overlapping notes, especially when lengthening notes
_, grid = reaper.GetSetProjectGrid(0, false)
for i = 0, reaper.CountSelectedMediaItems(0)-1 do
    item = reaper.GetSelectedMediaItem(0, i)
    for t = 0, reaper.CountTakes(item)-1 do
        take = reaper.GetTake(item, t)
        if reaper.ValidatePtr2(0, take, "MediaItem_Take*") and reaper.TakeIsMIDI(take) then -- Must validate to check for empty takes
            countOK, numNotes = reaper.MIDI_CountEvts(take)
            if countOK and numNotes > 0 then
                ppq = reaper.MIDI_GetPPQPosFromProjQN(take, 1+reaper.MIDI_GetProjQNFromPPQPos(take, 0))
                newNoteLength = 4*ppq*grid
                reaper.MIDI_DisableSort(take)
                for n = 0, numNotes-1 do
                    noteOK, _, _, startppqpos = reaper.MIDI_GetNote(take, n)
                    if noteOK then
                        reaper.MIDI_SetNote(take, n, nil, nil, startppqpos, startppqpos+newNoteLength, nil, nil, nil, true)
                    end
                end
                reaper.MIDI_Sort(take)
            end
        end
    end
end
reaper.Undo_OnStateChange2(0, "Set note length to grid length")

Will test this during the weekend!!

Thanks a ton JS!!

From my short testing it works brilliantly Julian. Thank you!

If you have a means for accepting donations then please let me know, I'd be happy to do so.

I have to say of all unique and fascinating things about this particular DAW, I think the most appealing is actually the community that continues to support and augment it.

Agreed on all counts. 1) JS is amazing. 2) I would have abandoned Reaper long ago if it wasn’t for the help from this community.

Just came across this thread as it's something I've needed for my workflow and wanted to say - Thanks for this script Julian! The Reaper community is fantastic.
