Audio Units failing in Mainstage

I have Mainstage 3 and have patches with heavy use of Audio units (Arturia, Spectrasonics, UVI, CherryAudio, EastWest, Sampler, Alchemy).

Everything is working fine but occasionally I get a pop up saying Audio Unit has failed....Recover/Close.

Recover usually works (takes a bit of time which is not good in the middle of a gig, but occasionally pressing Recover crashes Mainstage....definitely not good.

I have run auval -a when the pop up appears but don't understand what I am looking at.

If I am editing sounds in Mainstage I can generally get the problem to appear pretty much at will. Very annoying.

Aside from auval -a, is there any thing I can do to check what AU would have thrown the error?

I have killed all unnecessary apps that might have been running in the background just in case the problem was a memory one but that doesn't appear to have helped.

I'm running a 2022 M1 Pro MacBook 16" with 1TB SSD and 16GB Ram with Ventura 13.4.1.

Any suggestions or advice would be greatly appreciated.

I don't use Alchemy. By default, it is located here ~/Music/Audio Music Apps/Plug-In Settings/Alchemy. You could delete it and, if you actually use it, download again. Hope that helps.

Just had another failure... Two overlaid patches (Omnisphere and Arturia CS-80V4) stopped working. I pressed Quit on the error box and when I restarted Mainstage the Arturia CS-80 V4 was working but the Omnisphere patch wasn't.

Omnisphere is showing as being fully up to date and when opened independently worked.

While the Audio Unit error pop was showing I ran auval -a but it didn't show anything that I would interpret as an issu with either AU.... snap of what auval -a showed for these two AU's....

aumu Ambr GOSW - Spectrasonics: Omnisphere

aumu BuEa Artu - Arturia: Buchla Easel V

aumu CMIv Artu - Arturia: CMI V

aumu CSV3 Artu - Arturia: CS-80 V3

aumu CSV4 Artu - Arturia: CS-80 V4

aumu Clav Artu - Arturia: Clavinet V

Restarting Mainstage recovered everything.

Totally perplexed !!! :0

Hi tfromtroon

my sincerest apologies for not getting back to you. The latest story is I am still seeing AU failing pop-ups with Mainstage. All AUs seem to be compliant as far as I can tell.

What I now find when the pop-up appears, most of the time when I click RECOVER, the pop-up tells me Alchemy is reloading. Is this a problem with Alchemy? Is there a way to reinstall Alchemy?

Regards

Are all the AUs you are using M1 compliant?

What was changed in the setup when this started to happen (if anything)?
