Vln vibrato vs. open string no vibrato

I have a passage for solo violin that plays stopped notes against an open string. If I put no vib over the open string then it makes both voices non vib. I even tried adding a stave and transferring one of the voices there but I still can’t get both techniques to work. I’m using latest versions of Dorico and Noteperformer. Thanks

Make sure the two voices are set to separate “instances” (MIDI sounds/channels/slots). Otherwise one playing technique will apply to both.

Thanks for the reply Derrek.
