Komplete Kontrol krashing my DAW

Ugurcan

Hey there,

Running Komplete Kontrol is crashing my DAW.

Around a minute after I load a project with a KK instrument inside, Reaper's UI freezes first, then go unresponsive. Although I can still hear sounds and use MIDI input, no recovery happens.

When I check the process, I see it's blocked on Network I/O. Then I check the Network usage, I see Reaper trying to access 3 local ports (7865/5563/5146), which are being listened by NTKDaemon.

One particular library that hangs is Spitfire Audio/Albion Solstice / The Callers / Main Techniques. Switching between articulations definitely propagates the crash.

Things I tried to have a fix:

• Reinstalling, clean reinstalling Hardware Connection Service and Komplete Kontrol
• Plugging off my S49MK3 keyboard
• Disabling all DAW extensions like DrivenByMoss
• Restarts after each change

Any leads from here?

Windows 11 10.0.22631 / Komplete Kontrol S49 MK3 / Reaper 7.15

Responses might be few and far between…what we might need is a Reaper/DAW extensions person to come here.

I'm no such expert, but maybe it will help if you tell us about your hardware:

• CPU
• GPU
• How much memory
• Power supply wattage
• Audio and MIDI interfaces, and how they are hooked up
• If it's a laptop, tell us make and model, and include the above if appropriate.

Maybe that will get something going for you.
