It seems impossible to use “instrument change” when instruments use different number of staves.
Is that final? Is there no workaround this?
Is it possible that there is NO efficient way (instrument change) to notate that the percussion player plays a two-stave vibraphone, then a one stave percussion item?
Is it possible that there is NO efficient way (instrument change) to notate that the piano player leaves the keyboard to play a small one stave instrument, and then return to the piano?
