Music library and playlists

Bulk import your tracks, sort them into categories, build a playlist, use repeat modes and set the master volume in the Music Library.

You can run your music right alongside your lights, in the same app. This guide takes you through the Music Library screen end to end: bulk importing your tracks, sorting them into categories, building a playlist and reordering it, playing the list with its repeat modes, and setting the master volume.

Open the Music Library

  1. Click the Music Library card on the home screen.

    Home screen, Music Library card not yet clicked

The screen has three columns: Categories on the left, Tracks in the middle and Playlists on the right. The top bar holds the Master volume slider, a repeat button, stop and play. The library is empty for now.

Bulk import your tracks

For a single file, Add track is enough; for several tracks, Bulk import is faster. MP3, WAV, OGG and M4A are supported — pick files one by one, pick a whole folder, or drag files onto the window.

  1. Click Bulk import.

    The Music Import Wizard opens on the Source step, with Pick files and Pick folder buttons

  2. Click Pick files and choose your tracks in the window that opens.

    Pick files highlighted; below it, 4 files selected appears

  3. Click Next.

    Preview step, four track names and category pickers listed

  4. Click Next again.

    Options step, Skip duplicates checked, Also create a playlist unchecked; the Import button for the next step is highlighted

  5. Click Import.

    Import complete screen, 4 added badge visible, Close button highlighted

  6. Click Close.

    Wizard closed, the highlighted Tracks column lists four rows, each with --:-- as its duration

Track durations show as ”—:—” in the list — that’s not a bug, duration just isn’t calculated on import. A copy of each file is added to the library; the source files stay where they are.

Sort tracks into categories

As your tracks pile up, categories keep things tidy.

  1. Right-click All tracks; click New folder in the menu.

    The New folder dialog opens, name field empty

  2. Type House into the name field, click Create.

    A House category now appears under All tracks in the Categories column

  3. Click Select; click the “Deep House Electroanimals”, “Summer Deep House Yurasoop” and “Tech House Sound of Freedom” rows.

    Three rows now highlighted as selected, button reads Selected 3

  4. Click Selected 3, click Move to category, then click House.

    The three tracks now show House as their category; the rows are still selected and the button still reads Selected 3

  5. Click House in the left column.

    The Tracks column now lists only the three House tracks

  6. Click All tracks.

    All four tracks are listed again

After the move, the three rows stay selected; click the X to the left of Selected 3 to clear the selection.

Right-click a category and you can also turn it into a playlist in one step (Create playlist from category). The same track can sit in more than one playlist.

Build a playlist

  1. Type Evening into New list name, click Create.

    Evening (0 tracks) now appears in the Playlists column

  2. On the “Chill Tech Bearstock” row, click the Add to playlist icon, then click Evening in the menu.

    The Evening list now shows 1 track

  3. The same way, add “Deep House Electroanimals” and “Tech House Sound of Freedom” to the list.

    The Evening list now shows 3 tracks

  4. Click the Evening list’s Expand arrow.

    Tracks in list expands: Chill Tech Bearstock, Deep House Electroanimals, Tech House Sound of Freedom in that order

  5. On the “Tech House Sound of Freedom” row, click Move up twice.

    Tech House Sound of Freedom is now at the top of the list

The Remove from list icon only takes a track out of this list — it stays in the library.

Play and use repeat modes

  1. Click Play on the Evening row.

    The first track is playing, the Evening row is highlighted, the top bar shows a pause icon

  2. Click the repeat button in the top bar once.

    The repeat button is now outlined in blue, meaning it is on; the status reads Playing

  3. Click Pause in the top bar.

    Playback paused, the button has switched back to the play icon

  4. Click Play in the top bar.

    Playback resumes, the button has switched back to the pause icon

With the repeat button off (Stop after current track (no auto-advance)), the playing track stops at the end and doesn’t move on — useful if there’s talking or an announcement between tracks. Click it once, and you get Repeat entire playlist: the list plays in order and starts over at the end. Click once more for Repeat current track only.

Set the master volume

  1. Drag the Master volume slider down to about 60%.

    Master volume slider at about 60%, percentage reads 60%

  2. Drag it back up to about 80%.

    Master volume slider at about 80%, the percentage reads 79%

This slider only affects the music’s level; your lights stay as they are. The MASTER fader on the Live Control screen dims the lights and leaves the music alone — two separate controls.

What’s next

To sum up: bulk import your tracks, sort them into categories, build a playlist, pick a repeat mode, and set the level with master volume. The music keeps playing when you switch screens, so you can head to Live Control and run your scenes alongside it. Next up: Sound-to-Light, making your lights react to the music.
