The default playback method used with divisi and Independent Voice Routing has a glaring issue-
When you split violins divisi, you are splitting a violin section into smaller units.
If you take 16 players and do 4-way divisi, then naturally you would split 4+4+4+4, and therefore want the playback to be done with 4x instances of small ensemble/chamber strings. So, this is achievable with the current method (add the divisi and use IVR), but we have a problem when bringing the strings back to unison in the score: the playback will only occur on the 1st voice, thereby only constituting 4 players, and not all 16. For the playback to work properly, it should then output the unison line to all 4 voices assigned under the IVR (therefore playing back the whole string section, not just 1/4th of it).
Is there a preference or setting somewhere that deals with this?
