You should. I have set up this example and in the example, I have used "cresc." in two ways.
1. The first crescendo works from <em>p</em> to <em>ff</em>. I done this by attaching the start of the "cresc." to the <em>p</em> and the end of the "cresc." to the <em>ff</em>. In this case, I can hear both a volume change and an articulation change.
2. The second "cresc." is open starting from a dynamic start point of <em>p</em>, but not attached, and over the time that it lasts, it increases in volume, but drops back to <em>p</em> after the duration of the "cresc.".
The first is more controlled and does not rely on a random curve based on the amount of time that passes. You get more control that way rather than in the second example.
I am guessing that you have one of two possible problems happening.
1. There are velocities set on the notes. If velocities have been mapped, dynamics have been overrided. Press the TAB key on your ASCII Keyboard to see if there are velocities on your notes. If there are, there will be colored Sequencer Overlay lines on each note. If they have not been written, the Sequencer Overlay will appear gray.
2.You have not extended the dashes for the "cresc.", but instead, you have just inserted it into the score not specifying any duration. It should look like this: cresc._ _ _ _ _ _ _ _ _| up to the place where you have ended the "cresc.
I have attached my .notion file for you to test with, and an audio file that displays the playback that I am getting from this test file.
