> Disclaimer

Intrinsic Dev’s drivers are created to the highest standard developed with industry leading practices.

By installing this driver, you agree to our full Terms and Conditions, a copy of which can be found at the end of this document.

> Driver licence

This driver requires a licence to function. Pricing and licences can be obtained by visiting https://www.intrinsicdev.com/. Licences are issued on a per controller basis. You only need a single licence for multiple installations on the same controller.

This driver is powered by the Intrinsic(Athena) cloud and will auto detect if you have obtained a licence for your systems MAC address.

If you have not already obtained a license it will show an error. Please navigate to www.intrinsicdev.com to rectify and within a few minutes of order completion the driver will update and activate. You do not need to enter any information manually or make changes to the driver.

> Driver configuration

Ensure you have downloaded the latest version of the driver from: https://www.intrinsicdev.com/

> Device setup

Recommended Action: Static IP

Before attempting integration onto a RTI system, ensure the KEF speakers have been configured and tested stand-alone using the ‘KEF Connect’ app, this includes signing into your music streaming service accounts.

KEF IP - Enter the IP Address of the KEF speakers you wish to control.

The IP address can be found by opening the players IP in a browser – Current Network Settings.

Enter the IP address via Driver Properties – Connection, as shown below.

Poll info update rate – Select the rate from the drop-down list that you wish the driver to request data to update the UI.

Audio source

Volume level

Mute status

Play mode (shuffle, repeat)

If the KEF speakers tend to be controlled by other devices simultaneously short repeat rate is recommended. Increasing the repeat rate will ease the CPU usage on the RTI processor. Recommended – 5sec. Track metadata polls every 3 seconds.

Select Poll info update rate via Driver Properties – Poll info update rate, as shown below.

Streaming Services – Select which music streaming services have been signed into via the ‘KEF Connect’ app so only these are displayed in the browse item UI list. Incorrect selection here will result in a blank page after a service that is not signed into is selected. If you wish to sign in or create an account with a service later simply tick all selections now and then after returning from the ‘KEF Connect’ app the service will be active for browsing.

No form of sign in or set up is required for Radio or Podcasts. These will always be displayed in the browse item UI list.

Select Streaming Services via Driver Properties – Streaming Services, as shown below.

Debug – Available via RTI diagnostics in browser. Set “Driver – KEF” to High.

> Integration Designer11

Button Mapping – Button ‘Tag’ system supported (Integration Designer 11). Most buttons will auto map to RTI’s “RTI Music” template but for those that do not (or if you wish to build a custom UI) add a macro via the Macro List, drag Command across to the Button Properties window, click <select a device> and select KEF, you can now select the functions provided via the driver. Please see the ‘KEF-Example.apex’ file for a custom template / UI design start point utilising all driver features.

> Transport Controls Tips

Play and pause is the same command - “Command – KEF – Keys\Keys – PlayPause”. To achieve the dynamic UI design of the button icon changing from ▶️ to⏸️assign the command to 2 separate buttons, one with the play icon and the other with the pause icon. Assign the PauseStateOff variable to Visible via Button Properties to the button with the pause icon and PauseStateOn to the button with the play icon. Finally, stack them on top of each other, play on top of pause.

This step can be repeated for mute on / off. Both buttons assigned with the Mute command. Mute off icon (highlighted in red below) stacked on top with the MuteStateOff variable assigned. ‘Playing’ icon stacked below with the MuteStateOn variable assigned.

Design TIPs:

Add a bitmap / cover image behind the Dynamic Image for AlbumArt so when audio has stopped or if a track does not provide cover art then this will be displayed to the user instead.

Select Text Wrapping - Scroll Slow Non-stop if your text fields are narrow in case of long song names.

> Text Variables:

AlbumName

ArtistName

BrowsePath

PlaylistTitle

serviceSelected

TrackLength

TrackName

Volumelevel

The Volumelevel text variable can be found via Edit Button Text – Insert Control Variable – KEF – Volumelevel. This same process can be repeated for all other text variables. Placeholder sample text has been assigned to text variables to help with UI design layout.

> Visual Highlight Variable

To achieve the optional UI design feature of displaying a green circle (or highlight of your choice) around standby, service or source icon buttons that are currently active, a set of Boolean variables are provided.

Similarly, to Mute and PlayPause, place the visual highlight behind the icon and assign a Visible variable from the list. Make sure to match the name of the variable with the icon.

TIP – Use the serviceSelectedServiceX variable if you wish to highlight an ‘undefined’ service such as AirPlay.

Commands for changing source - “Command – KEF – Keys\Keys – wifi (etc)”. Optical is also called Coaxial for some KEF speakers. Setting to Optical will cover source changing and active highlighting functionality for Coaxial.

> Play Mode

RepeatAll and RepeatOne have to be separate buttons. Pressing RepeatOne will turn off Shuffle and RepeatAll. Shuffle and RepeatAll can both be activated for ShuffleRepeatAll.

Shuffle, RepeatAll and RepeatOne variables are available to assign to Reversed. This will show when the button is activated but only if a different Active Image is assigned in Button Properties. In this example only the button background changed upon activation and as shown below, the shuffle icon button is placed on top of this background button.

> Browse

If unable to add a Two-Way Item List to the page use the Page Wizard to temporarily add the Music Player and copy and paste the Two Way Item List box with Tag Browse. You can now assign the BrowseList variable to List and Select Browse Item variable to Command and select Index in the Dynamic drop-down.

Text Wrapping in Button Properties does not seem to affect the results displayed in the list so make sure the width of the box is wide enough to cover the average song title length.

Under Objects drag your desired Two-Way Item List commands to buttons. In this example I have used Scroll Down, Scroll Up, Scroll to Bottom and Scroll to Top.

Additionally “Command – KEF – Keys\Keys – browseStart” (home) and “Command – KEF – Keys\Keys – browseBack” need to be mapped to buttons for controlling the Two-Way Item List UI.

“Command – KEF – Keys\Keys – PlayNow” plays everything in the current view as long as it is a playable container. If it does not play, click forward another step and try again.

Selecting a playable track plays it and adds it to the global “PlayQueue”. The PlaylistTitle text variable as well as displaying the current playlist will also display “Playing Queue” if you have left a playlist / album (container) and are now in the “PlayQueue”.

“Command – KEF – Keys\Keys – ClearQueue” will stop playback if you’re currently listening via the “PlayQueue”.

> Additional Tips

On sending the driver to the processor for the first time after selecting a service no results will be displayed, navigate back either by BrowseBack or BrowseStart and then select the service again, it will now display results correctly.
