Standard notation player

The standard notation player is our interactive music notation technology. Learn about it on the features page.

How can I create music in Soundslice?

Create a free account account and visit your slice manager.

If you run a for-profit music site, you can license our technology to embed it in your own site.

How do I get my music notation/tab into Soundslice? What formats do you support?

Create a free account and upload a file in one of our supported formats:

  • MusicXML (exportable from Sibelius, Finale, MuseScore and many other programs)
  • Guitar Pro (.gp3, .gp4, .gp5 or .gpx)
  • PowerTab (.ptb)
  • TuxGuitar (.tg)

If you’d like to give Soundslice a quick test without needing to create an account, check out our free MusicXML viewer.

Which notation-editing programs do you recommend for creating MusicXML?

Sibelius and Finale are the two industry standards, and both have a native MusicXML export feature. Note has some Sibelius/Finale plugins that offer an improved MusicXML export over both applications’ defaults; we recommend those plugins.

Sibelius and Finale are quite pricey, so if you don’t already have them, we recommend checking out MuseScore, a free and open-source notation editor that works on Windows, Mac or Linux. It has good MusicXML export capability.

As mentioned previously, check out our free MusicXML viewer to give Soundslice a quick test.

Do you have any special features for music teachers?

Yes. With a Teacher account account, you can create a curriculum of interactive sheet music, upload audio/video clips to sync them with notation and assign lessons to students. It’s pretty great, and we’re adding new features all the time.

Slice management

Here are answers to common questions about managing slices.

I use Sibelius. How do I use Soundslice?

Export your notation as MusicXML, then upload that MusicXML file to Soundslice using the slice manager.

I use Finale. How do I use Soundslice?

Export your notation as MusicXML, then upload that MusicXML file to Soundslice using the slice manager.

I use Guitar Pro. How do I use Soundslice?

Upload your GPX (or GP3, GP4 or GP5) file to Soundslice using the slice manager.

Note that Guitar Pro offers a MusicXML export. Don’t use that, because Guitar Pro MusicXML files exclude some of the guitar-specific notation. Upload the native GPX/GP3/GP4/GP5 instead.

We support files created by any version of Guitar Pro starting with version 3.

I haven’t yet decided on a notation program. Any pointers on what works best with Soundslice?

If you’re using Soundslice for fretted instruments such as guitar, we recommend Guitar Pro because our importer has 100% support for importing its advanced notation such as bends, slides and harmonics. Sibelius and Finale don’t necessarily export those notations correctly in MusicXML.

If you’re using Soundslice for other instruments, ensembles or voices, try Sibelius, Finale or MuseScore (which is free!). Each of those programs can export MusicXML. One bit of advice: for Sibelius and Finale, install the latest MusicXML exporter plugin from — it does a richer export than the native export.

Soundslice displays notation differently than how it appears in my notation editor (Sibelius/Finale/whatever). What do I do?

We ignore all positional information in your MusicXML file — including line breaks, space between systems and slur positioning. That’s because our notation automatically wraps to fit whatever device you’re on. Our software might, for example, decide to put two bars in each system on a small screen, vs. five bars in each system on a larger desktop monitor.

If there’s a different (non-positional) aspect of notation that Soundslice isn’t displaying properly, please tell us about it! We are keenly interested in improving our software to deal with the thousands of corner cases of music notation. Please email your notation file to and let us know the problem.

How can I limit my slice to use only a part of a video or audio file?

In the syncpoint editor, click “Crop.” You’ll get an interface that lets you specify the start and end points of your video or audio.

How can I change Soundslice playback to swing eighth notes (or sixteenth notes)?

The answer depends on the format of your imported notation.

For MusicXML:

  • If your slice contains a graphical sign for swing feel (Triplet feel notation), then we will automatically detect it in many cases. If we don’t automatically detect it for you, please email the MusicXML file to so we can improve our importer.
  • Failing that, simply put the text “swung eighths” or “swung sixteenths” above the first bar of the slice. Our importer will do the right thing. Note that you can put the text “straight eighths” later in the slice to turn off the swing feel.

For Guitar Pro: Use Guitar Pro’s “triplet feel” setting in your notation.

For PowerTab: Use PowerTab’s “Triplet Feel” setting, accessible in the “Tempo Marker” menu.


I love Soundslice and want to help! How can I help?

[Yes, we actually get this question a fair amount!]

Awesome! Here are a few things that would be a great help to us:

I run a music education site and would LOVE to use this technology. What do I do?

Email immediately! :-) We do license our technology to other companies. Check out the whole page we put together on the topic.

Can Soundslice create sheet music/tabs automatically, given audio/video?

For now, no — everything’s manual. But adding an automated first-pass is on our to-do list and will likely be a pay-for feature.
