Playback Tempo Inconsistent after 1st measure

• Jun 15, 2015 - 20:51

We have exIsting templates for all different time signatures. And we have the same Playback tempo problem in all of them. What happens is the Play Back tempo works correctly (follows the metronome marking) for just the first measure at best, then it seems to revert to the default (see 4.4. TEST 1). To correct this, we end up entering a 2nd metronome/tempo marking at the end of the 1st measure or beginning of the 2nd measure to reiterate the original tempo, since it doesn't appear to hold or didn't "take" (see 4.4 TEST 2). That seems to fix the issue, but we shouldn't have to do that.

Any ideas why this is happening?

As often happens to me ... I do not know why but:
I clicked on the first measure, Add / Measure / Insert one measure;
I copied the measure 2 (now) in the first;
Click on measure 2 press Ctrl + Del.
See if it works well

So basically something is screwed up behind the scenes in the first measure. So you insert a new first measure. Then delete the old first measure, which is now the second measure. When I copied the old first measure into the new one, it didn't bring the Tempo/Metronome marking with it. So had to reenter it. It used to be that I could get the Playback to work fine with just one metronome marking at the beginning BEFORE closing the score. Then upon closing and reopening the score, the problem would return.

So I tried closing and reopening after setting up the new first measure and deleting the old, and it appears to be working. The tempo is performing as expected, which is consistently on Playback.

I think we may have found a solution!

You're right, that's exactly what you use templates for. But what are you doing with your template files? If you put a score in ~/Documents/MuseScore2/Templates, then when you create a new score it will show up as a template you can use in the new score wizard, just like the default templates do, and you can choose any time signature you like for a score created from it. Try it and see how it works.

We have different users of our templates who access them through Dropbox. Looks like we could set everyone up in Preferences to access them from there. However, we have specific pitches and note heads that vary in some lines depending upon the time signature. Don't think the Wizard would get that right. Also since we only use the linear or "continuous view" exclusively and need the score to look picture perfect in that view, we have to manually enter the measure numbers, as they don't show up there at all unless you're scrolling the score within the software which tells you what measure you're on.

Basically we're not using Musescore like most people do.

Wow! I'm getting really curious to know what exactly your project is. Certainly the "Pictures at an Exhibition" scores that you posted on #65356: Mixer Duplicating Instrument Voices were very interesting. Be that as it may, it does sound like the regular template system wouldn't serve your purposes.

It seems, though, if I understand this right, that you may actually have discovered a bug with regard to copying and pasting measures containing tempo markings. So, congratulations and thanks for that. ;-)

As to measure numbers, here's a tip: you can control when and how often measure numbers appear from the Header, Footer, Numbers section of the General Style window. No manual work needed.

Never got back to you about what we're trying to do.

We use only the "Continuous" linear score. Never use Portrait. And I know of no way to show measure numbers in that view without adding them manually.

We actually need to export images (or a video) of the linear scores, which is also difficult since we'd like an easy way to output the entire horizontal score, instead of having to use a series of screen shots.

Thanks.

Odd. It actually speeds up just at the end of the first measure ie BEFORE the second measure starts (copy and paste tempo from Measure 1 to Measure 2 and you can here it on playback).

I right-clicked on the tempo marking and chose "Select all similar elements" and pressed [Del]. Then I added the tempo marking back in and it played fine so somewhere (near the end of Measure 1) there appears to be a rogue tempo mark.

I then exported the original as an XML and there IS a rogue tempo mark near the end of Measure 1 but it's a tempo without an visible text or note. I do not know how it got there.

There is indeed a mostly-empty tempo marking at the end of the first bar in the original file. This could happen in 1.3 if you added tempo text, then removed the text but didn't delete the actual element. In 2.0, these are normally converted to regular text with the metronome marking, but set to invisible. That didn't in work in this case because the tempo text isn't *quite* invisible - it still contains the tags setting the (non-existent) text to bold. So the mechanism that is supposed to show you the invisible tempo markings isn't kicking in here.

Even so, you can always remove these by right clicking the first (visible) tempo text, Select / All similar elements, then press Delete.

If these are invisible (or even "not quite invisible") how are you seeing them? Did you export as .mscx and view in a text editor? I tried that but couldn't tell what I was looking at.

The Select/All similar elements to delete does work. Playback is normal. I think I'll use that to fix the templates instead of inserting a new measure at the beginning, copying the old first measure into it, and deleting the original first measure.

Thanks!

Basically, yes, I looked the MSCX in a text editor. I did a search for "Tempo" and say one entry at the beginning of the score and another towards the end of the first measure.

FWIW, though, I didn't actually use Save As, though - I used the MSCX that is already within the MSCZ file. You can open an MSCZ in any ZIP program and examing its contents.
