I have 130 or so bars of drumline in quavers, semi,-demi--hemidemi quavers and want to change them all to a specific side stick , maintaining their values, without going over each one of them by hand. I marked them all and tried but nothings works. Is the a way to do it with one click , or two?
Make sure that specific side stick is a defined note in your drumset definition.
If you can select them all (for example via right-click on one and select > more > "same pitch") then you can use the up/down arrow keys to cycle them between the defined notes of the drumset.
