If someone is still searching for a solution, I found one, albeit not the easiest or fastest way :
- I use the voicemeeter plugin which allows me to use my computer soundcard output as an input.
- I create an audio mono track on the project and put it in solo mode (or mute all the other ones).
- I activate the metronome and record on the created track.
- I reset my sound card configration to the one I used on Cubase
As I wrote, it’s real-time and ask to do multiple things instead of a single click… But as a Cubase 9 LE Elements user, it’s the only way I found…
