Plug-Ins missing in the mix console

Hi, i have Dorico pro 3,5 and all my plug-ins on windows 10 are in the list normally.
But on Dorico 4 the list is empty (just empty files) but all my plug-ins are missing.
i suppose i have done a wrong manip but now, witch files from 3,5 can i copy to v4 or witch file on V4 can i erase to restore the list please.
i have try “reinitialise plug in” and “audio engine” but no changement after this.

in Roaming file, i see a file audio engine v3,5 and a other audio engine v4 is it normal ?

thank you for your help

kid regards,


In regards to the plug-ins you don’t need to copy anything around.
D4 shall “see” the same plug-ins as D3.5, so I wonder what is happening on your machine.
Please do in both, D4 and D3.5 from the menu Help > Create Diagnostics Report and post both files here. Be aware though that the one diagnostics report will overwrite the other, so make a backup copy before doing the next.

And that what you see in Roaming is normal.

Uploading: Dorico Diagnostics…

Sorry but i have tried here and by mail but the Max size is 4 MB so my zip files are too big

Can you send them one at a time?

5,2 MB and 8,2 MB

is it possible via mail at a other adress ?

If you send them to u dot stoermer at steinberg dot de be sure to include a link to this thread so @Ulf will know where to check for background

i have received this message:

Or can you upload to Drop Box or some other file sharing service?

I have sent you a private message, please check.

Sorry i have writen" stroemer"

Thanks, I’ve received it and am now looking…

So the logs tell me that both, D3.5 and D4 detect plenty of plug-ins, VST2 and VST3. I have not watched in detail, but roughly spoken it is same. So if you go in Dorico 4 to the mixer window (F3) there is nothing in the list of effect plug-ins?

Are you aware of the VST & MIDI Tab in Dorico 4’s Play mode? I think that has changed since version 3.5 as part of the Play mode overhaul. That tab is where one adds VST’s to each project, presumably to help individual projects be more efficient by calling on fewer VST’s.

No i don’t know this. and i confirm, there is no plug in in the mix console
