I would love to be able to play a guitar part in and it returns a detection of the chords as the basis for chord track though. I generally don’t use Variaudio/Melodyne as correction - i use them for drafting ideas and creating a ‘perfect’ template for what we should be aiming for.
…I then ‘try’ to record live takes based on that signal being put through headphones. But, then i don’t like a ‘perfect’ sound… I like humane mistakes to be a part of the music.
That’s why i would like to see it added into Cubase. But as Chizzler touched on above, it’s probably another company who develop the detection algorithms and Steinberg will just pay a license and interpret those functions into use in the software. Studio One is very good at doing that already.
