My intention was to notate a series of bars in which the percussionist is instructed to play random notes with glockenspiel mallets on a bell tree. I have got as far as creating the wavy line which I reckoned would serve as showing the duration of the action:
Then I intended to remove the rests and write a suitable description. But - the rests refuse to be removed (even if I select all the rests for every instrument in the Percussion player list for the bars in question). When I checked against the part, in case they were removed there, I saw that the wavy line wasn’t shown at all:
Evidently I’m going about this the wrong way. How should I be achieving what I’m looking for?
