I’m using EastWest Symphonic Orchestra for playback. The 18 Violins master keyswitch set has no entry for muted violins or col legno battuto; these effects have to be loaded as distinct instruments.
Having a “player” keyswitch on a single instrument for particular articulations works great, but what is the method for automatically having a “player” switch to a different instrument entirely during playback? I can see the two other instruments that I’ve assigned to the “player” underneath his rollout in Play mode, but they’re never actually used for playback, despite my having placed articulations in the score that I’d want to trigger those piano rolls. (The MIDI channels assigned to these instruments designate expression maps that have the articulations defined in them, and they correspond to the instruments that I’ve loaded into EastWest Play, where their channels match the channels defined in Dorico’s Play interface.)
The following images illustrate my set-up:
