I am a new Dorico user so I hope this question is not to stupid. In large scores where a group/system of instruments do not play for at least a whole page is there a way to remove them to save space. Ex: A large symphonic section is followed by a solo oboe section. I would want to remove all the instruments except the oboe which plays for at least a page. Can this be done? Any help would be appreciated.
Sure. Layout Options > Vertical Spacing > Hide Empty Staves. See https://steinberg.help/dorico_pro/v3.5/en/dorico/topics/page_formatting/page_formatting_staves_hiding_showing_empty_t.html?hl=hide%2Cempty%2Cstaves]
It’s also possible to handle it on a more local basis, using Staff Visibility Changes. See https://steinberg.help/dorico_pro/v3.5/en/dorico/topics/page_formatting/page_formatting_staves_hiding_showing_manually_t.html
