For all who want a smaller dynamic range and get more realistic playback of hairpins, there is a different approach to using the dynamics Sibelius sends. Be aware that this will take more CPU power and more samples are streamed at the same time from your hard drive.
For dynamic changes Sibelius sends CC11 (MIDI Control Change 11) values. These values by default are triggering the Expression slider in the Vienna Instruments. In order to get more realistic crescendi and diminuendi you can do the following: Go to the Perform page in the Vienna Instruments. Activate Velocity X-Fade. Then Click on Map Control. Now as source for Expression set none. Then go to Velocity crossfader and as source select ControlChange/Controller 11. Repeat that for every instrument you want this to take effect. Don't forget to save your Playback Configuration in Sibelius after that.
