Does anybody know how to fix this error message seen in Logic?
It appeared the for first time when I tried to test a 5.1 surround six-channel config with the hex tracker using the AUv2. I have since changed back to a regular mono input, but this error message persists.
Full disk access has been granted to the host and the standalone app. The AUv2 opens in other hosts, no problem.
Strangely, some old projects with the MG3 plug-in will load correctly some of the time. Others wont. It’s rather unpredictable.
Audio Inception must already be present (not active) when Logic creates MG3’s hosting environment, and removing it withdraws the broader filesystem access that MG3 is relying on.
I have not reproduced this MG3 AUv2 failure in any other macOS host; it currently appears limited to Logic Pro. However, because the problem emerged during Audio Inception development — and Audio Inception’s sandbox declaration directly determines whether MG3 can open — I suspect my plug-in or my recent sub-hosting tests may have created or exposed this state in Logic. I’m reporting it because I need help understanding what my implementation may be doing to Logic’s AU hosting environment, not because I’m assuming there is a defect in MG3.
Aha! Thank you for this detective work. This is something that puzzled me for a long time and related to various issues with plug-ins inside plug-ins. I will try to make some test with other entitlements to see I’d that change anything.
I have the same problems with MIDI Guitar 3 in Logic and yesterday the pop-up screen appeared that I’m using the trial version of MIDI Guitar, which is not true. I paid for it.
I think that the problem started with the latest mac update(last week)and i hardly use any otherDAWs so I don’t know about that.For now I use it in the sandbox way which I don’t prefer buts it’s usable.
Me too. I personally didn’t use Logic very much up until recently. I have tested various plug-ins in it over the years though, and I don’t recall having these exact problems in the past.
