The explanation lies in the way Sibelius allocates sounds. Sibelius determines how to 

allocate a staff based on the sound IDs available in the sound set, the Best Sound de-

fined in the instrument staff’s settings, and any manual sound set or Preferred Sounds 

directives present in the playback configuration. This is repeated for each staff in the 

score until all staves are allocated to an appropriate device and sound.

Manually selecting a sound or device in the mixer tells Sibelius “Use this sound regard-

less of any other setting.” This overrides the entire allocation system, and while Sibelius 

will still work within the system, it’s forced to ignore certain things in order to comply 

with the manual assignment made in the mixer.

The trouble caused by doing this is not often obvious, in fact, depending on the 

complexity of the library or device, problems may not appear right away. Nevertheless, 

since there are ways of controlling and guiding sound allocation within the system, in-

cluding manual sound sets, Preferred Sounds, and instrument staves, it’s best to utilize 

the methods provided rather than “brute-forcing” and overriding the system through 

the mixer.
