Tks for taking time out to reply, Andi. It's really appreciated. Sometimes it feels like troubleshooting the old christmas tree light: it takes only 1 dead lamp to create the problem but finding it is something else.
Yes, I'm using the latest SibeliusSoundsets-WIN-1.0.194 and the "Vienna Symphonic Library" House Style (Appearance -> Import -> Vienna Symphonic Library" and all "Import Options").
I'm loading 03 Synchron Elite Strings, preset "01 VelXF sus MOD".
The Sound set used in Manual Sound sets is "VE Strings", and the instruments, in the strings category, are "Violin n|Viola|Violoncello|Double Bass [VSL Synchron Strings]
The program names in Sibelius Playback devices are Synchron Violins|Violas|Celli|Doublebasses Pro"
The score doesn't mix up different ensemble string types.
I did notice two things. (1) the first has to do with Velocity X-fade. What is the default CCn assignment for Sibelius in the Perform Tab of the Synchron Player -- and where is that documented? E.g., for all Elite string instruments I have Expression=CC11 and Vel.XF=CC1. That's probably because in the past I was using VI Instrument pro rather than Synchron player. I also tried changing Expression to CC2. For all string instruments the CC1 slider moves about with the written dynamics or expressions, hairpins and all - except for... the double bass (it doesn't move).
(2) I also noticed that, by default, some cells were disabled when loading instruments. So string pizzicati were played as Short Notes -> Staccato since the "G# Pizzicato" was disabled. I enabled all cells in the Synchron Player settings and now the celli (and other strings) play the pizz articulation instead of staccato -- except for (you guessed it) the double bass! It simply doesn't move.
