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.

Slices

For our purposes, a slice is a single instance 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.
Also on this page, specify privacy settings for the slice (paid accounts only).
Next, specify embedding preferences (licensing partners only). See the separate Embedding section for details.
Finally, specify printing preferences (paid accounts only). If you enable it, users will see a “Print” button in the slice settings.

Notation

Once you’ve created a slice, you’ll see it in the list in the slice manager. The next step is to add notation. You do this by uploading a notation file — something you’ve either acquired or created in another program such as Finale, Guitar Pro, MuseScore, PowerTab or Sibelius — or by using the notation editor that’s built into Soundslice.

If you already have a notation file, here’s how to upload it. We support a handful of different notation file formats: MusicXML, Guitar Pro (versions 3-7, including GPX), PowerTab and TuxGuitar.

Find the slice in the list, and click its title.
On the subsequent page, select a file to upload and click “Upload the file.”
When it’s done uploading, view the notation rendered in Soundslice by clicking its name in the slice manager list. You can listen to it (using our default synthetic instrument samples), transpose it, hide parts and more.

Recordings

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.

Find the slice in the list, and click “Add a recording.”
On the subsequent page, specify the name. This is what people viewing your slice will see in the “Recordings” menu.
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 soundslice.com.
If your slice has multiple recordings, reorder recordings using the up and down arrows in the slice manager. This ordering will be used in the “Recordings” menu. Whichever recording is last will be the default.

Syncpoints

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.

Find the recording in the slice manager, and click “Create syncpoints.”
The subsequent page is the syncpoint editor. On top, you’ll see a waveform display of your audio. Below, you’ll see the slice (or blank space, if you haven’t uploaded a slice yet). Note there are separate playheads — the vertical orange lines — in both places.
The first time you load the syncpoint editor for a recording, it won’t yet have any syncpoints. Hence, if you press Play, the orange playhead in the notation won’t move; it doesn’t yet know how the audio and notation are related.
To create syncpoints, press Play and click “Add downbeat” — or hit the T key — on each downbeat, i.e., the “one” of every measure. You’ll see a black circle appear in the waveform, representing the syncpoint at the start of the measure.
Once you’ve added syncpoints, the orange playhead above the notation will line up with notation according to the syncpoints you’ve created. This gives you immediate feedback on how your syncpoints influence the synced playback.
You can also add syncpoints while audio is paused. Click anywhere in the waveform, then click “Add downbeat.”
To move a syncpoint, click and drag it left or right. To delete a syncpoint, click the “X” below it. Click “Clear syncpoints” to delete all syncpoints and start over.
To change a syncpoint’s measure number, double-click it and type the new number. Use this technique to save time by creating only a few syncpoints (watch demo).
For expressive music, syncpoints on the downbeats might not be enough. You can fine-tune inner-bar syncpoints by dragging the “guide notes” above the waveform left and right. Read more.
Save your changes by clicking “Save” at upper right. Changes won’t be saved until you do this.
To copy syncpoints between recordings, go back to the slice manager and click the “Copy syncpoints” button for the recording whose syncpoints you want to copy. Then select the recording to copy to. Optionally, you can specify the time offset in the destination recording at which the first syncpoint should be copied; this is useful if the recordings are identical but one of them starts a bit later.

For more on the syncpoint editor, watch this overview video. Then watch this second video to learn about the syncpoint-renaming shortcut.

Folders

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.

Embedding

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. example.com. Note that www.example.com and example.com 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.
To delete a recording, click its trash icon.
Get an embed code for your slice by clicking “Embed.” You’ll see some HTML code you can paste into your site. It works the same as a YouTube embed.
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.
