Managing content on Soundslice

The slice manager is a web-based tool that lets you create, edit and delete slices. This page explains how to use it.


A slice is a piece of music notation of any length. It might be a simple two-bar guitar lick, a 32-bar string-quartet piece, or even a full concert band score. It can have any number of instruments/parts.

Everything in Soundslice is oriented around slices. They’re the fundamental unit of the site.

Create a slice by clicking the “New slice” icon in the slice manager.
On the subsequent page, specify the name and, optionally, the artist/composer.
Then, you’ll see shortcuts to either enter notation or add a recording. You can do them in either order.

Notation / tablature

To enter notation in a slice, you have two options. You can upload a notation file — something you’ve either acquired or created in another program such as Finale, Guitar Pro, MuseScore, PowerTab or Sibelius — or you can use the notation editor that’s built into Soundslice.

If you upload a notation file, you can of course use the Soundslice notation editor to make tweaks to it.


By default, our player uses instrument samples to play your slice’s audio, with a MIDI-like sound. But Soundslice really shines when you sync notation with real recordings.

For our purposes, a recording is audio or video of a specific performance of a slice. With Soundslice, you can associate multiple recordings with a single slice.

When editing your slice, click “Recordings” at the top of the page to open its list of recordings. the slice in the list. If the slice has no recordings, you’ll immediately get the “Add recording” screen.
Choose the type of recording — a file upload, YouTube video, video URL or Vimeo video.
If your recording is an MP3 or video, upload the MP3 or MP4 file. It’ll be stored securely on


Syncpoints are how Soundslice aligns notation with audio/video. For example, a syncpoint means something like “The start of measure 2 in the notation corresponds to 0:05 in the audio.”

Use the syncpoint editor to create, edit and delete syncpoints. Each recording gets its own syncpoints, and Soundslice provides an easy way to copy them across recordings, if needed.

Here’s an overview of basic usage:

And here’s a video covering more advanced features and shortcuts:


Keep your slice organized by creating folders. You can create as many folders as you’d like, and folders can be nested within one another.

Create a folder by clicking the “Add a folder” icon in the slice manager.
Specify the folder name. It’ll be created within whatever folder you’re currently viewing.
To move a slice to a folder, click the “Move to folder” icon next to the slice, then select the destination folder.


Soundslice licensing partners get the superpower of embedding slices in their own sites. To embed a slice, take the following steps.

First, when creating or editing the slice, enable embedding. You have two options:

  1. Allowed on any domain
  2. Allowed on whitelist domains

If you’re concerned about keeping your content locked down, use the whitelist option for the most security. To edit your whitelist, visit this page (this page is only available for licensing partners) and enter the domain(s) your embed should be limited to, one domain per line, e.g. Note that and are treated as separate domains, so you’ll likely want to include both the www and non-www versions of your URLs if applicable.

Finally, get the embed code for a specific slice using the slice manager. Note you can tweak the width and height to your liking.

Bonus fun for developers: our embed player has an API.

More things you can do

To delete a slice, open the menu at far right of the slice’s title and select “Delete.” All of its syncpoints and recordings will also be deleted.
Download your original notation file (the one you most recently uploaded to this slice) by clicking “More,” then “Original.”
Export your notation in Guitar Pro format, regardless of your original notation format, by clicking “More,” then “Export GPX.” (Paid accounts only.) MusicXML export is coming soon.
Search for slices using the search bar at the top right of the slice manager. This searches the name and artist fields.
