The LUMIN App is designed to be intuitive to use without any training. Many users just download the app and start playing. However, the app has hidden depths and as more features have been added over the years and some elements may benefit from further explanation.
Sections
App Layout:

LUMIN App has three main panels:
- Browse: Explore and select from your music collection.
- Playlist: Once you've selected from the Browse panel, your music will be queued for playing here.
- Now Playing: This is where you can view and control what's playing now.
Browse:

Getting started:
- Turn all devices on, including LUMIN and your music server.
- Open the LUMIN App.
- LUMIN App will automatically detect your devices.
- Confirm your choice of server by tapping it.
- LUMIN App will find all your music and store all the artwork. Note that on the very first use of the App, this can take some time (approximately 250 albums per minute).

Sort the list by:
- Song Title
- Album Title
- Artist
- Composer (optional)
- Genre
- Year
- Newest added to the server

On this same menu you can also get access to Folder Browsing (Standard UPnP Browsing), TIDAL, Qobuz and Internet Radio (see down the page for more details).

Change the view:
- Artwork View (tapping on an album takes you to Song Grouping View)
- Song Grouping View
- Heading View
Note: The available views vary depending on current Sort/View combination

Maximise your view:
The browse panel can be maximised to fill the screen. Useful while creating large Playlists.

Pinch to zoom:
When in Artwork View, you can pinch the screen to zoom the artwork. LUMIN App will automatically rescale slightly to optimise the view.

Add to Playlist:
Normally, as soon as you tap on a song or Grouping header, it will automatically be added to the bottom of the Playlist.
However, if you have selected 'Double Tap' as the selection method, more options become available.
You can now select multiple single songs at once and the bottom menu will appear, allowing the following:
- Play Now: Add selection to the bottom of the Playlist and LUMIN will skip to it and play immediately
- Play Next: Add selection after the 'Now Playing' song and LUMIN will play it after the current song has finished
- Play Later: Add selection to the bottom of the Playlist
- Play and replace: Will replace the whole of the Playlist with selection, and starts playing
- Clear selection: This will deselect all songs.
To easily add a whole album to the playlist, see below.

Info Pop-up:
Press and hold on any item in the Browse, Playlist, or Now Playing app areas to open an info pop-up.
From this pop-up you can:
- Add this item to the Playlist (see above for icon explanations). A major benefit is being able to add a whole album to the Playlist without leaving Artwork View.
- Change the browse sort order, based on that item
- Search the current library for matching items
View the Last.fm entry for this artist/title
View the Allmusic.com entry for this artist/title
Browse the TIDAL library for matching items
Browse the Qobuz library for matching items
- When in TIDAL or Qobuz, you also search your local music library for matching items.
On the resulting pop-up you can press the Globe icon to switch to your tablet's main browser.

Search:
First select the tab to sort the list by (see above).
Then type in the word you want to find in that tag.
The example shows that we are searching for "Joni" in the Artist tags.
Playlist:

Album grouping:
To make the Playlists easier to understand, LUMIN App visually groups songs that are from the same album. Artwork is only included once per group.
The area highlighted in blue is one Album Grouping.
Now Playing song:
The song being played in the Playlist is highlighted in the left column by a play symbol instead of the Playlist number.
If the Playlist is long, you can quickly scroll to the Now Playing song by tapping the 'Jump' button.
The 'Jump' button displays the Now Playing song number and the total number of songs in the Playlist.

Edit:
Tapping the 'Edit' button will change the appearance of the Playlist songs. You can now tap the red 'Minus' icons to delete a song/album from the playlist, or drag the 'Grip' area on the right to re-arrange the song order.
When you have finished, you can tap the 'Edit' button again to return to the normal Playlist view.

The 'Playlist' button (highlighted) is used to both Save and Load Playlists.
Save new: Type in your new Playlist Name in the text box and then tap the 'Save' button.

Notes:- The least signal processing occurs at level 100.
- When less than 100, the default volume control algorithm is Leedh Processing.
- The number displayed may be higher than the actual volume due to the Max Volume % setting. e.g. This volume ring is 80, but the Max Volume % is 70, then the actual volume is 80 × 70% = 56.
- The Volume Ring can be hidden in settings if it is not required.
