Just whilst on this subject, I noticed an issue when running VSTi only plugins (i.e. no stanfalone) inside Cantabile for the first time that required registration (noting that Cantabile is my only host on the live PC).
E.g. in UH-E synths (VST only) my user name is (boringly) “Derek Cook” but I couldn’t type that as every time I hit the SPACE bar between the words the key event was consumed and the Cantible playback started!
I had to write “Derek Cook” in notepad and copy and paste that into the registration dialog for the synth running in Cantabile, if that makes sense.
Not a deal breaker, but I thought it worth mentioning.
