In the VDL 2 Template, there are 4 lines of Treble Clef Marimba.  What's the easiest way to switch it to a Grand Staff and still ensure playback will be correct.

Which program, Sibelius or Finale?

In Sibelius, click on the first measure you want to change and press 'Q' to change the clef.

In Sibelius, you can also go to the Instruments and Staves menu under Layout and add the Grand Staff Marimba under pitched percussion.

Or just hit ";I"; and the menu will appear as well.

Marimba staves in the VDL2 templates (Finale and Sibelius) are simply pitched, 5-line staves. There's no percussion mapping involved, so you don't have to worry about any sort of playback getting damaged by adding the grand staff, and deleting the existing one if you'd like. Whichever notation program you're using, the user guide should have pretty simple directions on how to do this.

Thanks Guys.  It worked.  I just added the Grand Staff Marimba and told the Mixer Window to go to the proper VDL2 Channel.  Thanks for the input.

Anybody knowledgeable for how to do this for VDL 2.5.5 and in Sibelius 8??? I know I'm in the minority for that combination of software but still thought I would try. Thanks!

The process is the same as noted above.
