Recently I downloaded the full version of Cubase 10 Pro.
On my computer are also Cubase 7 Pro and Cubase 9 Pro.
Since Cubase 9 Pro I sometimes have the problem that files are missing from sounds of Halion Sonic SE or drum kits of Groove Agent SE.
This is an intermittent problem. The same sound / drum kit is sometimes there and sometimes missing.
How can I solve this problem?
