CleanMyMac / Clean My Mac sometimes erroneously detects KLANG:app as BirdMiner malware

faq icon to expand accordian

KLANG:app containers are tested before uploaded to the download section of this website. CleanMyMac sometimes erroneously detects KLANG:app as BirdMiner malware. We can assure that this is a false positive and our developers have reached out to the clean my mac developers to resolve this warning on their end.

There is no need for additional tools such as CleanMyMac and they are known to cause performance issue. Please ignore this warning.

Why do KLANG show files and log files have a time offset?

faq icon to expand accordian

KLANG uses UTC timestamps throughout to support devices with multiple time zone settings simultaneously. This explains why you see a constant time offset.

See details here to determine the offset:

Do I need a WiFi router? Which kind is best?

faq icon to expand accordian

You only need a WiFi router, if you want to connect KLANG:app on smartphones or tables, e.g. for personal mixing or for a monitor engineer when working on the stage. A hardwired ethernet connection is always the best choice for critical communication links, e.g. when running the DiGiCo console integration. We recommend to use a hardwired ethernet connect whenever possible, especially for laptops or computers with an ethernet port.

There are two different frequency bands for WiFi – 2.4 GHz and 5 GHz. We recommend to use dual band WiFi routers or Access Points. The 2.4 GHz band might get very busy or noisy when several mobile devices are around. The 5 GHz band tends to be the better choice. In many systems it is possible to define unique SSID to the 2.4 and 5 GHz bands, so it is easy to see on a mobile device on which band you are working on. Modern mesh routers are more intelligent and tend to provide the best performance in all situations.

Error Code 5 with webroot on Windows

faq icon to expand accordian

This is a known issue with webroot.

Solution: get in touch with your system admin to disable webroot.

Why do I loose connection to the KLANG processor with a 10G network adaptor?

faq icon to expand accordian

Newer Mac computers might ship with a fast 10G network adaptor. This adaptor sometimes runs into communication issues if the connected device (e.g. a network switch) does not support 10G. In that case a significated percentage (e.g. up to 50%) of the network traffic might be dropped, but it is hard to troubleshoot as it still works from time to time. This issue has not been addressed properly by the manufactured of these computers, yet.

Solution: Use a USB Gigabit network interface.

What is KLANG’s software update release and product support philosophy?

faq icon to expand accordian

KLANG products are designed to be used for long periods of time and our philosophy will always be to try our best to offer support for as long as it is needed; however, this might become limited for various reasons, for example where we are depending on third party component suppliers, soft- and hardware developers etc. Our legacy products KLANG:fabrik (introduced in 2014), KLANG:vier and KLANG:quelle 19” are still receiving updates today, following this philosophy.

KLANG does not rely on rigidly fixed software update cycles (e.g. once or twice a year). Instead we aim to constantly maintain and improve the user experience, especially by releasing KLANG:app improvements to react to changes in smartphone or computer operating system updates as soon as possible.

Find the latest software updates here.

How many :apps can be connected to KLANG immersive processors?

faq icon to expand accordian

Our products are designed and tested to be used with at least 1 :app or :kontroller per mix, plus 2 :apps for engineers. In most cases is is possible to use even more apps, there is no fixed limit.

How can I listen or CUE into mixes?

faq icon to expand accordian

All KLANG immersive processors allow for CUEing into all available mixes. This is particularly helpful for monitor engineers that need to constantly switch between mixes. Details on the CUE functionality can be found here.

Which DiGiCo consoles offer the KLANG console integration

faq icon to expand accordian

The KLANG console integration is available on the following DiGiCo consoles

  • SD series
  • Quantum series

Do I need a control computer for the DiGiCo console link?

faq icon to expand accordian

Yes. The KLANG DiGiCo Console Link requires a computer running KLANG:app for setup and for operation.

Is there a way to decrease :kontrollers Display brightness or turn them off?

faq icon to expand accordian

Yes, you can activate Dark mode/:kontroller blackout which turns all LEDs and Displays (except for the last one)off. This is particular useful for theatres when the stage should be as dark as possible. With a push on any rotary button, the dark mode can be exited. [KKA-120]

In order to revert all :kontroller back to normal operation, use “Switch lights back on”. Follow this link for more details.

Do I need special headphones or in-ears to experience 3D sound?

faq icon to expand accordian

No. KLANG incorporates binaural technology and processes the sound inside a KLANG processor to work with your own pair of standard stereo headphones or in-ears. In fact, it is not important if your headphones are open or closed, electrostatic, dynamic or use balanced armature drivers as most in-ears do. You can use universal fit in-ears or custom molded in-ears. Just make sure that the polarity is correct and the left and right signals go to the correct ears.

Is it Personal Monitoring System or is it a tool for Monitor Engineers?

faq icon to expand accordian


The KLANG system is designed to be very easy to use especially if you don’t have years of experience in mixing monitors. The 3D in-ear mixing functionality enables musicians to get a very transparent and natural in-ear / headphone mix and a very short time.

At the same time, our products and especially KLANG:app offers all features experienced sound engineers or monitor engineers expect when working with a mixing tool for the live or studio market. Especially features like CUE mixing for musicians is a feature you want to use at mixing monitors constantly.

Why are all other groups turned down if I increase the volume of one group?

faq icon to expand accordian

KLANG:app and KLANG:kontroller offer customizable DCA groups for an improved mixing workflow e.g. during a show. By default, the volume of all other groups is decreased when the volume of one group is increased. This helps to keep the sound pressure level approximately the same and prevent the mix to get louder.

However, if you want to deactivate relative DCA group mixing go to KLANG:app > CONFIG (requires Admin mode to change this setting) > INFO > SET > Disable KLANG:app Relative Group Mixing

In order to change the behavior for KLANG:kontroller login with KLANG:app to your KLANG:kontroller (requires Admin mode to change this setting) > INFO > SET > Disable Relative Group Mixing.

How many channels and groups can be adjusted on :kontroller

faq icon to expand accordian

:kontroller always supports all groups of a mix. The maximum number of groups per KLANG mix is 16. By pushing GROUPS on :kontroller the first 8 groups are shown and by pushing GROUPS for a second time the last 8 groups are shown.

:kontroller supports 3 banks of 8 channels each, so the first 8 channels of a KLANG mix are available. It is important to sort the most important channels that should be controlled to the first 24 in the KLANG mix. However, the groups can always control the channels 25+. It is also possible to hide channel from the kontroller, without the need to resort channels. Hidden channels are still audible in the mix but cannot be individually tweak. However, if the group is changed in level these hidden channels will follow.

What do the red or green icons above CONFIG stand for?

faq icon to expand accordian

What does a yellow or orange “M” and red “S” in FADERS mean?

faq icon to expand accordian

If any channel in a mix is on solo, a red icon with “S” for solo appears  just above the FADERS menu icon.

If any channel in the mix is muted a yellow or orange icon with “M” appears.

How do I exchange presets between different processors?

faq icon to expand accordian

Presets are interchangeable between all KLANG immersive processors.

If the presets contains less input channels or less mixes these settings will be added from the default file. In case the preset has more mixes or more input channels than the processor offers the first mixes and first channels will be loaded until the maximum is reached.

How disable and enable the built-in demo mode feature

faq icon to expand accordian

It is possible to generally disable demo mode. This is particularly useful to prevent the demo mode button to appear in case KLANG:apps are disconnected from KLANG hardware network. Users might click the button accidentally and not notice that they are now mixing the built-in demo song instead of their own in-ear mix.

To disable, go to ADMIN mode and log in to a KLANG:fabrik/KLANG:vier mix or the built in demo mode. Then, navigate to CONFIG > INFO > Set (button) > Advanced > DON’T show demo mode. Fully restart KLANG:app. Now the demo mode will not be listed in the CONNECT screen anymore.

To enable again, go to ADMIN mode and navigate to CONFIG > CONNECT. Press and hold the refresh ICON (circular arrow at the bottom) for 4 seconds.

Which Characters are allowed for Preset Names?

faq icon to expand accordian

Preset names shall not include blank spaces or any special characters such as  \“#@,;:<>*^|?\\/ etc.

Allowed characters are ‘a–z’, ‘A–Z’, ‘0–9’, ‘-‘, ‘.’, ‘_’

Can I remote control the system via MIDI or OSC?

faq icon to expand accordian

Yes, that is possible.

KLANG:app, all KLANG processors and :kontroller exclusively communicate with each other via OpenSoundControl (OSC) messages. Find all details about the OSC messages in the OSC Reference Guide.

KLANG:app can further be controlled via MIDI / MCU.

There are also flexible third party converters from OSC to OSC or MIDI to OSC available, such as OSCulator. In this way, mixing console commands like snapshot recall or fader comnands can be converted. Additionally, tools like touchOSC can be used to design specific graphic interfaces if required.

Does KLANG:app support multi-touch?

faq icon to expand accordian

On iOS and Android multi-touch is inherently supported. On Windows KLANG:app can be used with a multi-touch display, i.e. several faders and icons can be moved in parallel. However, on Mac OS X multi-touch displays are not supported as such. Hence, only a single fader or a single icon can be moved one after another.

– We are currently working on a solution for this and work around the barriers of Mac OS X –

Do I need an iPad, Tablet or Smartphone?

faq icon to expand accordian

It depends. If you want to use the KLANG processor a personal monitoring system all musician should have access to their mixes.

This can either be done with KLANG:app on smartphone or tablets or with KLANG:kontroller. This works of course at the same time, it’s completely your choice.

Licensing Error on Amazon Tablet

faq icon to expand accordian

The Digital Rights Management (DRM) is sometimes causing an issue on Amazon Tablets. The tablet need to be connected to the internet from time to time to renew this license. DRM might be deactivated in future KLANG:app releases for the Amazon AppStore. To workaround, please connect the tables to the internet at least once every month.
