Scanning Audio Units Every Time App is Open

Dorico

Dorico is scanning Audio Units every time I open this app. Is that supposed to happen? Is there a way to prevent this?

Well, yes. Dorico initially does a deep scan of all plugins and caches the meta data so that on subsequent starts, it just scans for changes. This means, a fresh install or an invalidated cache will prompt Dorico to do a full scan.

Are you seeing very long scans consistently every time you start Dorico?

I think WaveShell is the usual suspect.

Not very long, but many scan every single time I open Dorico.

Is there a course of action I can take to prevent this?

Remove the VST.

Hi @Keaton-Viavattine ,
looking at your log files, I see that you have 275 plug-ins that potentially will get scanned at start-up, but it only takes 9 ms in your case, because there is cached info around for each of the plug-ins, so actually none of them gets really scanned, just the cached info compared and this all in 9 ms. So, even if you would delete all of the plugs, you would not gain any speed at start-up.
P.S.: And Dorico makes no use of AU plug-ins, it only can deal with VST plug-ins.

I just timed it at 10 full seconds. Something seems off to me.

10 s is not unusual. What kind of spec does your machine have?

It’s not a big deal to me if that sounds normal. I have a Mac Studio, M2 Max, 96 GB RAM

I’ve just tried with my M1 MacMini and the first start-up took 9 sec until the hub window appeared.

Every subsequent run took around 7 sec until the hub.

But it also depends on how many and what kind of plug-ins you have, so can’t always compare.

Cheers
