So I've just discovered the cresc./dim plugin in Sibelius 7.5 to apply to sustained rolls using anything longer than quarter notes. I've had success applying this plugin to a long dim. buzz roll, but now I'm not having any success applying it to the picture attached, where the hairpins are more frequent with the buzz rolls. The rolls just sound flat. I know that you can type out 16th notes and add a tremolo on each note, but it sounds too mechanical- I'm being picky because I am sending this piece off for publication and want it to sound great. Any help is greatly appreciated. I am using the VDL "Concert snare drum" and a Write Score template. Thank you!
