Maschine 3 software crashes out of now where

It's been a while for me that I didn't use Maschine as standalone app. The crash happens when I add instruments or effects, nks compatible or not.

Did you try the Maschine crashes or freezes trouble-shooter ?

Yes was the first thing I tried. I also doubled checked that the plugins to be compatible with my OS.

Does it also crash as standalone ? Also then what is your DAW and DAW version ?

No DAW today. Just standalone. I will check with the DAWS I have installed and post here if it helps.

Plugins that maybe are causing the crash:
- Izotope: Neutron 5 EQ or Ozone 12 EQ, specially Neutron if it's on more than one sound Maschine gui becomes unresponsive and everything plays out of time.

- Eventide Blackhole if the plugin GUI is open and clicked on the presets menu Maschine SW crashes immediately.

- Ableton 12: Maschine as plugin, opened old project with Pigments, Serum2 and Massive inside Maschine with drums group some sounds with maschine internal drum synth and other samples, no issues so far. the fx are used from ableton side.

- Bitwig 6: Maschine as plugin with only drum synths inside and all ok.

@Jeremy_NI , I think that this might need your expertise .

A question popped in my head. since Maschine SW requires full disk access (as the rest of NI sw) does all plugins should have full disk access enabled? I checked Eventide installation instructions now and they don't mention anything…. Also Xfer. Arturia plugins does requires it and I have it enabled since I've done the updates. I tried to use other NKS Instruments from u-he and works fine, without full disk access.

Ah , I misunderstood you. I thought that Maschine 3 crashed by itself. But what you say is that it crashes when opening other plugins ?

Another thing then if using Sequoia/Tahoe then N.I. apps (and other audio apps) must be added to the Local Network (Ref.: How to grant audio apps access to your local network on macOS 15 Sequoia)

No worries, probably I didn't explain it well forgetting that Maschine can be used inside other daws 😅
in the post title I mentioned that it's crashing either I use vst3 o au, but I referred to is vsts or au inside Maschine SW as standalone app. I'll edit it now.

I can't add applications to access local network from anywhere. the apps should request access. I have reinstalled reaktor, maschine, kontakt thru native access and they didn't request permission…. The only thing from NI that has local network access is NIHostIntegrationAgent.

Do I need to go and dig into hidden folders and do all sort of hacks now.

You can't add applications to the local network permissions. If an app needs that access it will request it and MacOS adds it to the permissions list.

i know… maschine, reaktor, kontakt and kk never requested access. I remember when I updated ableton after update it has request access.

mykejb

I think the "everything needs local network access" goes back to when the MK3 keyboards came out and it was a requirement for those. The 'everything needs Full Disk Access' is another permission that I've never needed to grant to every app under the sun, and my Mac runs fine.

Jeremy_NI

@sam__kk Sorry I'm a little confused. Can you describe step by step the events leading to the crash?

Yes I remember that. I have no NI keyboards just Maschine MK3. I don't feel comfortable giving full disk access to any app…

I have run Maschine SW in debug mode and heres the output.
