Since I remember, I had always this issue with groove agent. When I choose a sound… some files are missing !
Since Cubase 5, I had never use this plugin because of many sounds not found by this VST (and with different windows computers).
But it was only with the groove agent SE ! So I was thinking during all these years that it was because of this light version.
But with my last Cubase 9 pro purchased (last version updated), I decided to buy absolute 3 with the last groove agent 4 (but not only).
Everything is working fine with Halion 6, sonic 3 with all sounds… and also others VST I have… my list is impressive : NI ultimate 11, East west, Nexus, VPS Avenger, Ivory II, Spectrasonics, Maschine studio, etc.
I read on forums that it is better to reinstall Cubase with the check box “for all users”.
So I did it and reinstall Cubase and Absolute 3 completly.
But nothing more with this weird issue. And only with this … hem special software.
So if you need some idea to improve steinberg products… please do it first with this … sofware.
My version is 4.2.30 in Windows 10 (last version too).
And for your information, I am a software developper since > 30 years.
So if you have to explain something to understand (even complex) how to use this curious VST do not hesitate. I can do anything on my computer.
I also tried to copied some .vstsounds files into the specific groove agent directory… double click on the interface, search and modify on all directories etc. etc. etc. and so on!
