I don’t understand why being able to move the instruments around within the rack makes any difference – you can easily move them around within the project window, for various purposes, incl grouping. I do it all the time. The order in the rack is irrelevant
The VST rack has multiple issues imo. A few more pretty obvious ones …
Unless you just turn on all outputs at once you have to keep navigating back to the same menu if you only want the first 8 of a 16 output synth turned on. That’s 7 trips into the same menu (for outputs 2-8) to do something that should probably be (in Cubase) on a small dialog?
Still no presets or templates that capture the multi-output settings for things there.
Not being able to look at the rack and know which instruments are currently in use - connected to something - and which aren’t. I mean, this is software right?
Most of that stuff is many years old as relates to being requested by users.
I’m fairly sure there’s a little blue dot on the instrument rack that lights up if an instrument receives midi data? I know that’s not ideal, but better than nothing at all.
