Hey musicullem, I downloaded the 5.5.10 version tonight and had a successful remote session. Everything not working in 4.0.45 is working in 5.5.10. 'create", “remove” vst connect works just fine. Seems to be a compatibility issue with C11.0.41 and VST 4.0.45, at least on my system. The one thing I noticed in 5.5.10 is that the talkback stays on even when recording starts. ( I wasn’t in rehearse mode). Is this new in 5.5.10? I can turn talkback off and on at will, recording or not recording, but I liked the feature that it automatically muted my talkback while recording.
BTW: Windows 10 2H21, Cubase Pro 11.0.41 , i79700k, Asus z390 prime, 32 gig DDR4, Interface is Allen And Heath GS-R24 firewire.
PS, I did create an empty Cubase project with just VST Connect 4.0.45 and got the same problems.
