There is a Cubasis manual. It describes how to set up a metronome countin. But the description is wrong. One has to go dig out the answer in an online forum to find how to do this seemingly simple task.
What about the idea of manual writers who proofread their work and keep it up to date as new features appear. Now, I found the answer to how to get the countin in a 2017 post, so definitely, there’s been time for that manual to be updated.
Cubasis comes with an (off-line) in-app help, plus additional online version. Please check one or both of these resources, and let us know where the description fails.
