The Soundslice Blog

Soundslice now supports proportional notation — a way of spacing music such that all notes take up the exact same amount of space according to their rhythmic duration:

Visual overview of proportional notation

Proportional notation is useful for beginner musicians and for people with dyslexia. It also means the playhead moves at a constant rate during playback, without the normal ebbs and flows. For more pros and cons, see our new help page.

This option is available on all music sitewide. To enable it for a given slice, open the Settings menu, switch to Horizontal layout and check the “Proportional notation” checkbox:


Your notation will instantly be reformatted to use proportional spacing.

You can also control the base proportional width — how much space is allocated for each note. Simply slide this control left and right to adjust on the fly:


If you’re in a paid plan, we’ll automatically save your proportional notation settings on a per-slice basis, so that they’ll be restored next time you access the slice.

Embed the Soundslice player in your website via our Licensing plan? You can now customize its colors.

We’ve added an embed styles section to your account settings. There, you can change more than a dozen aspects of our player’s colors, from the main background color to more subtle things like secondary colors in the Settings menu.

Have a look at the new help page for more information, including diagrams of each aspect of the player that can be customized.

Here are a few examples of custom colors in action, for inspiration:



You can now move and delete slices in bulk! This feature was sorely missing from our slice manager.

To move multiple slices to the same folder, click their icons to select them, then click “Move” in the resulting pop-up menu:


The same works for deletion:


Hope this saves you time. For more info, see the updated help pages for folders and deleting slices.

Since beta-launching our PDF and image importer a few weeks ago, we’ve been surprised at how many people have tried to upload tab-only music. That is, music that looks like this:


Problem was, if you tried to upload this, you’d get an error: “No noteheads detected.” Our system required that there be standard music notation attached to the tablature.

Given so many people tried uploading this style of music, we’ve made it a priority to handle it. Now, if you upload a PDF or photograph of music like this, it’ll (hopefully) actually work!

But there are several caveats. The biggest caveat is that we currently import all notes as quarter notes, because our machine-learning algorithms don’t yet know how to determine the rhythmic duration of each note. We’re working on that, but we figured we’d launch this early version since something is better than nothing — and note durations are easy to change in our editor.

For more about tab-only support in our PDF/image import, see our new help page.

We’ve launched a few improvements this week:

Automatic syncpoints

Soundslice can now guess the syncpoints for your audio and video!

You’ll now see an “Auto sync” button in our syncpoint editor:


The button is grayed-out until you’ve entered three syncpoints. Create at least three accurate syncpoints at the start of your audio, and the button will activate.

Once the button is activated, click it and we’ll populate the rest of the syncpoints. That’s it!

This works best for music with an obvious rhythmic pulse. For music with lots of rubato, your mileage may vary. In any case, why not just give it a try and see what happens?

Note this feature is limited to users in a paid plan. For more, including tips on how to best use it, see our new help page.

New metronome sound

We’ve improved our metronome so that downbeats get a different sound than non-downbeats — making it easier to keep track of where you are.

This also applies to our count-in feature.

Hide bar numbers

You can now opt to hide bar numbers in any slice you’ve created. Use the new “Hide all bar numbers” checkbox, which appears if you click a bar number or click the “Override bar number” editor command.


More info is in our updated help page.
