Checked in here and saw @darkstar01uk update, so I tried installing latest RackPro version, 2.5.2. I have Bitwig updated to 5.2, running same old version of Ubuntu Studio. After a bit of trouble tracking down all the various places I needed to update files, it seems to be working properly. Tried CLAP and VST3 version. So, if anyone else had similar issues in the past, might be worth checking again with updated version. If I run into problems, I’ll update the thread.
