Can we make a script that would place the control line in C11 in the play tab, then C1 or C21, etc?.
Not easily, I don’t think, no, because there is at present no keyboard access to these user interface elements. However, we know that it would be useful to be able to both display multiple MIDI controllers and to save and recall sets of lanes, and these are features we plan to implement in future versions of the software.
Yes, it is necessary. In fact, the development of all this part of the automation (I’m talking about the interface, because the possibilities are already there) will give Dorico users bigger wings.
