I’m running into a reproducible issue with Kontakt 8 + Circular in Maschine 3 that I haven’t seen clearly answered elsewhere.

After this, Circular’s audio became corrupted (buzzing/distorted, incorrect sound). Removing iZotope plugins does not fix the issue. I attempted to reset Circular using Kontakt’s Purge functions, but: * Purge All Samples on a single Circular instance fails * Purge All Samples across all instances fails * Purge state remains “red” / inactive * Playing through the project once or multiple times does not cause samples to reload * Corrupted sound persists Expectation: Based on Kontakt documentation, purging should allow samples to reload cleanly after playback. That never happens here. Questions: * Is there a known issue with Kontakt 8 purge behavior in Maschine 3 on Apple Silicon, especially on macOS Tahoe? * Are Circular (generative / round robin) instruments expected to behave differently with Purge, or should purge still work per instance? * Is there a documented interaction or known risk when using iZotope Neutron/Ozone with Kontakt instruments in Maschine that could lead to persistent corruption? * What is the correct way to fully reset a Kontakt 8 instrument in Maschine so samples are reloaded from disk?

Kontakt 8 (Circular) audio corruption when using iZotope Neutron 5 + Ozone 12 in Maschine 3

I’m running into a reproducible issue with Kontakt 8 + Circular in Maschine 3 that I haven’t seen clearly answered elsewhere.

System:

Maschine 3.4.1
Kontakt 8.8.0 (VST3)
Circular 1.5.1
MacBook Air 15", M4 (2025)
macOS Tahoe 26.0.1
iZotope Neutron 5.5.1
iZotope Ozone 12 Advanced (12.1.0)

Issue:
While mixing, I used Neutron 5 and Ozone 12 on the master channel. After this, Circular’s audio became corrupted (buzzing/distorted, incorrect sound).
Removing iZotope plugins does not fix the issue.

I attempted to reset Circular using Kontakt’s Purge functions, but:

Purge All Samples on a single Circular instance fails
Purge All Samples across all instances fails
Purge state remains “red” / inactive
Playing through the project once or multiple times does not cause samples to reload
Corrupted sound persists

Expectation:
Based on Kontakt documentation, purging should allow samples to reload cleanly after playback. That never happens here.

Questions:

Is there a known issue with Kontakt 8 purge behavior in Maschine 3 on Apple Silicon, especially on macOS Tahoe?
Are Circular (generative / round robin) instruments expected to behave differently with Purge, or should purge still work per instance?
Is there a documented interaction or known risk when using iZotope Neutron/Ozone with Kontakt instruments in Maschine that could lead to persistent corruption?
What is the correct way to fully reset a Kontakt 8 instrument in Maschine so samples are reloaded from disk?

This is blocking multiple projects, and purge currently provides no recovery path. Thanks in advance!

Hello,

i can only try on windows and here it works fine, even if i wouldn´t mix within maschine, instead i would use a daw that can use all cores of your computer has a better mixer gui for that purpose. And purge/reload samples works fine here too. I guess you gave all rights needed to all native instruments programs otherwise they won´t work. Hopefully someone with a mac and os tahoe will chime in and help out here. You maybe could try kontakt stand alone with circular and try to purge/reload there?

but maschine is not officially supportet yet on mac os tahoe maybe that is an issue:

I like to do a quick mix when I've finished writing in Maschine 3, before I reconstruct and mix in my DAW. For me, it helps to take tracks on the road and live in them for a bit before I close the door on arrangements, it's a great way to commit. I like even rough sketches to sound decent.

The questions I'm asking here, if valid at all, are specifically related to Apple silicon computers and iZotope plugins corrupting audio in Maschine 3. I own the rights to all my NI and other tools.

Thanks for the reply Uwe303
