So, I am watching new features of Studio One 5.3 (free feature-update release just came out).
I am seeing a feature we are probably missing in Cubase 11 Pro?!
Stereo Audio Event > Right Click > Detect Chords.
In the lower part of the Event the chord names are now showing (how great is that already?!)
Another click and holding of a function key and drag down to empty space and a new MIDI file with the dected chords is created! Man, is that handy! Or can I do it with Cubase somehow too?
