You can’t do this directly in Cubase. However there is Key Command To Marker X which will open a dialog box for you to enter a number. Unfortunately Cubase Macros don’t support passing in a number. So you can’t build a Macro to go directly to Marker 11 for example. FYI, Cubase doesn’t have a proper scripting capability since the Macros can’t deal with stuff like variables & constants or logical decisions. Basically Macros let you string together Key Commands one after another and that’s it.
The target is to remote with midi controller. not by keyboard entry. Cubase 13 pro is able to read script, but it must be compatible. I know Cubase is not able to make direct script. It request external software. but I dont know wich one and how to do it.
