change all the 16th notes in the bass to half notes

• Mar 16, 2017 - 01:59

Ok I managed to import a midi, merge the staves, transpose the notes into right key, increase the system distances, (just about everything I asked how to do in the past in here.) and now I have a readable

but the original midi i used has wrong durations for the bass notes. I need to change all the 16th notes in the bass to half note duration.

How do I do that except to do it manually one at a time?

Do you just want to change the Noteheads to Halfs? That isn't too much work. Select all first 16ths and chnage the Notehead. But if you want real Halfs then you would need to use a different voice arrangement. Perhaps the first half-note in a bar voice 2 and the other 16th-notes voice 1. Of course the "second" intervals on the same string like in bars 8,9,14 etc. need a think over.
Ahem, if this is for guitar.
What I did on the attached score: select 2nd note with mouse, changed to 16th and assigned to voice 1. Did that manually for every bar.
Then select first note in voice2 and changed to Half Note. Then jump to next note with right arrow.

Musescore needs a filter for note positions and the ability to change durations of multiple selected notes.

musikai, If "a filter for note positions" means every middle C (as shown in your picture) that is going to be in 2.1 when it comes out.

I would like to have the ability to change durations on several notes at once. The problem is what does the program do when you select those first 3 16th notes in your picture and you press 6? The programmer must be able to decide MS's response to such a situation, but I don't know what it should do. Making it work like an insert would be a different response than changing the 16th notes on the first beat to 1/2 notes in this score.

You cannot put those notes into voice 1 because they have a different rhythm than voice 1. If you want them in a different voice than the 16th note, it is easiest to change the voice for the 16th notes (you probably want voice 4 so the stems point down). To do that, select the notes and press ctrl-alt-4 to change them to voice 4. The reason you cannot do this with the tied notes, is that you cannot change voices on individual tied notes, you must do it a measure (or multiple measures if the tie crosses measures) to include all of the tied notes and exchange voices. If you really want the long notes in voice 4, you can exchange voices 2&4 after you put the 16th notes into voice 4.

Sorry took so long to reply. I had horrible comp problems with updates not working and causing blue screen errors. This went on for a good part of the week. It's still ongoing but at least I can start the windows now. (this isn't related to musescore)

And you're right. I swear I did change the voice for the c's to 4, but apparently I didn't save it. What you're saying works fine now.


Here's what I did to show what I want to accomplish. I've reattached the score you sent with my modifications.

1. From bar 1-2, I've

- selected the tied 8th notes in voice 2 to change them to 16th, then

- deleted the quarters that were tied to them manually,

(because I couldn't figure out how else to do it. it might be the only way to accomplish that based on what you were saying earlier.)

This introduces a lot of rests in the voice 2 which need to be gotten rid of.

2. From bars 3-4, I did the same I did in bars 1-2, but also,

- changed the stem direction upwards to make it more inline with other 16ths.

3. From bars 5-6, I did everything above and then

- selected both voices 1 and 2 and changed them to voice 1 which made them into continuous beams.

(now I have more spurious rests)

4. From bars 7-8, I did everything above and

- got rid of the spurious rests by hand.

These bars 7 and 8 shows what the score should look like when finished. (more or less and many of you pianists would want to kill me after looking at it). This similar if not the same as the one posted by Musikai.

Now that's a transcription a beginner can tackle, starting at position 1 of the guitar. It gets harder at the ends which needs to be fiddled with as this transcription moves along.


5. From bars 9-10, I show another possibility of dealing with the tied notes, ie. to keep them. I've tried to assign the tied to notes to voice 1, but it doesn't let me...

This is a much harder transcription that involves playing at higher positions and bars.

What I would like to do is go back and forth between transcriptions shown in bars 7-8 and 9-10 fluently. So that I can produce 2 or more kinds of transcriptions as needed. One for the beginner and then advanced (which may also involve transpositions)

I hope that's somewhat clearer that my past ramblings.

how did you assign the second notes, e's and d's, to the voice 1?

As described above in my post ;-) I first changed the first e to 16th (key 3) and then applied to voice 1. (clicked the 1 on the gui. This always only works with one note selected.) Left over in voice 2 is the first c 16th and the remaining notes of e's. When chnaging this first c to half the remaining e-notes were overwritten.

You can change as many notes' voice at a time you want as long as they are not tied. You can click the first then press ctrl- and click each subsequent note, then tell MS to change voices. You can either press the 1 on the GUI as musikai said or if you prefer keystrokes press ctrl-alt-1 for voice 1 or any other number up to 4 for other voices.

As a bit of clarification, if all the the notes were consecutive, you could use the filter for the voice they are currently in click the first note, shift-click the last note to select everything in between as well, then use one of the above methods to change voices.

Perhaps you didn't know about the Open Well Tempered Clavier? It's always better to start with a MuseScore file rather than a MIDI if one exists.

You can take one of those files and copy the bass onto a new treble staff, exchange voice 1 with voice 4, then copy the original treble staff into your new treble staff. I've done this for you in the attached file. Now you just need to tidy it up a bit and work out what you want to do with the bits that are too low for the guitar.

Here's two more ways you can do it that look different but sound the same and are arguably easier to read. The first method uses ties instead of notes in different voices (see bar 1), and the second method (bar 2) just dispenses with the long notes altogether, since it makes no practical difference on the guitar anyway.

I just discovered the "paste half duration" (⇧⌘Q) and "paste double duration" (⇧⌘W) which are both under the "Edit" menu at the top of the screen. Worked wonders for me, hope it helps you and/or anyone else looking to "rhythmically transpose" a musical passage.
