My file has 4 staves and currently I have to select each staff and change the instrument. What I need is to select all the staves and change it to a common instrument at once.
Thanks to NWC Team for making a wonderful notation software.
Only issue that I am facing is that, have created a music sheet with 4 staff's (Two Right Hand and Two Left Hand). But on saving one of the left hand staff gets converted to right hand.
