Is there any way to show the chords of a song in cakewalk, like at the top of the marker section or..?.
Not that I know of and I've been with Cakewalk for decades.
Admittedly, I'm still parsecs away from being a power user.
If I'm understanding your question....if I want the chords to be viewed to remind me or for others to see if they're playing along I just create a clip, rename the clip with the chord(s) or another quick note.
If the progression is simple I may have (3) chords noted within the clip name.
Have a great day....
