This has been a feature in Cubase for many years. You can copy a plugin from one track to another by holding down “option” and click/dragging it to another track, to any insert position you want. To move an insert you can simply click and drag a plugin to another track and it will move to that track and insert position.
You are right. That one works whithin the mixconsole window, perfect!
I wanted that function for the arragement window, too.
I often use the “e-Button” for viewing the plugins.
And i have a shortcut for my external midi controller for that.
And then dragging from that window “Kanaleinstellungen” to another track in the arrangement window.
Actually i do not work with a permanent mixconsole window while having an external midi controller.
That´s my actual workflow for the moment…
