Dropouts on long notes only when offline rendering in Kontakt 7/Kontakt 6

I've been having a recurring issue with offline rendering Kontakt instruments since somewhere in the Kontakt 6 cycle (still happening on K7.)

Playback and online rendering works fine, as expected, but I get dropouts on long notes when offline rendering unpredictably. Short notes seem to work fine.

I get the same issue across multiple DAWs - Logic, Cubase and Reaper. I've tried across different OSs (Win 11 & MacOS) and different SSDs. It isn't a CPU/RAM issue either - this happens on both large and tiny projects. I've noticed it mostly affects orchestral sample libraries like Cinematic Studio, Rhodope, etc.

I've also tried -

  • Purged/unpurged Kontakt instruments.
  • Setting 'Offline Interpolation Quality' from Realtime to Standard.
  • Changing the amount of max voices played by the instruments.
  • Setting Kontakt's Multiprocessor Support from 12 cores to off.
  • Changing Kontakt's Instrument preload buffer size.
  • Changing my sample rate
  • Changing my buffer size.
  • Changing the 'bounce mode' in Kontakt.
  • Disabling/enabling 'anticipative FX processing' in Reaper.

Unfortunately nothing seems to have worked. If any of you have any ideas on how to fix this, I would be hugely grateful - I'm constantly wasting hours having to check through all my Kontakt stems and then re-export some of them online. Since it's such an unpredictable problem, it's really hard to avoid!

Thanks.

    For anyone coming across this thread - I spoke with NI support via email and I'm afraid to report that this issue is on NI's radar, but there's no timeline on a fix. NI support apologised and said the following:

    "The Bug is still open in our system. We are trying ti fix this issue, but as EvilDragon already mentioned in the thread, it is not so easy to narrow down the root cause and then implement the fix.

    I am sorry. at the moment there is no fixed build or version listed."

    Looks like we might have to be working around this for a while...

    Also suffering from this problem. Basically it renders some of the most expensive Kontakt instruments I have purchased from Native Instruments useless. This needs to be fixed!

    Happens on Cinematic instruments at least. Note dropouts and strange cuts when bouncing/rendering.

    If you have Kontakt open with its internal Keyboard visible, you can see that some of the notes in your notation are not being "pressed" at all on Kontakt's keyboard, while rendering.

    Yep, that's exactly what I'm experiencing. Looking online it seems like quite a few people have had this issue as well! Any devs on here that can weigh in on whether this is a Kontakt or library specific issue, please do.

    @inthevoid Are your libraries installed on an external hard drive? What is the format of that drive? What's the OS on your mac?

    @Jeremy_NI Thanks for getting in touch. Yep, samples are on external SSDs formatted to APFS. OS on my mac is Ventura.

    Worth mentioning I also have this problem on my PC (Win 11) which has the samples on internal NVMe drives.

    I thought this as well, but I've tried switching between Kontakt 5, 6 and 7 and have the same problem on all of them...
