KLANG:app on macOS shows only a black window and never starts
On some Macs KLANG:app opens a black window with the spinning wheel and never gets any further. There is no error message and no crash report, and reinstalling or trying older versions does not change anything.
The app is not crashing. It is waiting for macOS: one of the first things KLANG:app does at start-up is ask the system MIDI service for the list of MIDI devices, and on the affected Mac that service never answers. In every case we have seen so far the reason was a third-party MIDI driver that is not compatible with the installed macOS version, typically after a macOS upgrade. The Waves / SoundGrid MIDI driver is a known example.
1. Confirm it. Open Audio MIDI Setup (Applications > Utilities) and choose Window > Show MIDI Studio. If that window also hangs or shows the spinning wheel, the MIDI service is the problem, not KLANG:app.
2. Restart the MIDI service. Open Activity Monitor, type MIDIServer into the search field, select it and click the X in the toolbar to quit it. macOS starts it again automatically. Then start KLANG:app.
3. Remove the driver. If it hangs again, in Finder press Cmd+Shift+G and go to /Library/Audio/MIDI Drivers/. Move the third-party drivers in that folder to your Desktop (nothing is deleted, you can move them back), restart the Mac and start KLANG:app. If you have Waves or SoundGrid software installed, start with its MIDI driver, or disable the driver in the Waves software.
If none of this helps, please contact support with a sample of the hanging app: while the black window is on screen, open Activity Monitor, select KLANGapp, click the gear icon and choose Sample Process, then attach the saved file.
What is a link-local or zeroconf IP address?
It’s an automatic IP address in the range 169.254.x.y/16, assigned when no DHCP server is available. Devices can still communicate with each other on the same subnet.
If your KLANG system can’t find a network with a DHCP server (the box that normally hands out IP addresses, e.g. a WiFi router), it will just give itself a number automatically so everything can still talk to each other. These self-assigned numbers always start with 169.254… and are called link-local addresses (sometimes also called “zeroconf”). It’s nothing to worry about — your devices will still connect and work together. For bigger setups, engineers might introduce a DHCP server or may switch to fixed IPs, but for a quick jam or smaller shows, link-local works fine out of the box.
Can KLANG:app listen to custom OSC messages on a different port than 9111?
Yes, you can configure Custom OSC Receive Ports in KLANG:app:
Go to KLANG:app (5.6.7+ required) > CONFIG > INFO > Set Menu > Custom OSC Receive Port > and enter an additional port KLANG:app should listen on for incoming OSC messages, e.g. 9112.
What can I configure in the SET menu in KLANG:app?
The KLANG:app > CONFIG > INFO > Set Menu gives access to important configuration options for your local KLANG:app instance and the connected device, e.g. KLANG processor, another KLANG:app or a KLANG:kontroller.
Can I lock musicians to a particular mix on my processor?
Yes, that is possible. Go to KLANG:app > CONFIG > INFO > Set Menu > Musician Mix Lock
