I was also thinking about my current DAW, Logic Pro X. It would be lovely, for me personally, to have a DAW built around a scoring paradigm. There would be a score view and also a piano roll view. In the piano roll view there would be a hollow rectangle representing the "quantized" notes as written in the score and the colored filled in portion of a note would be the actual performed duration. One could edit the performance by adjusting the colored length, and one could edit the score by adjusting the enclosing hollow rectangle — thus, one could adjust the performance and/or the score from the piano roll view. If one were to adjust things in the score view, the piano-roll information would be "destroyed" and become fully quantized.

So that's how I wish things would work, and I would prefer that Dorico and Cubase were one program, where Dorico is "merely" an important view of the Cubase DAW. Anything else is a kludge when trying to use them together. Put another way, Dorico should start as a scoring app and grow into being a proper DAW.
