I noticed that when writing on a 5-line percussion staff, articulations such as staccato and tenuto must be applied to all notes on the stem, or none of them. If you want different articulations, you must first move the differently-articulated notes to an extra percussion voice. (There’s no such restriction for playing techniques.)
If you attempt to apply staccato to only one note of many that share a stem, for example by switching to an individual-line part, the operation will quietly fail. Could it be possible to allow the operation, and instead automatically move these differently-articulated stem-sharing notes to extra voices as necessary?
This could work even in the pathological case, where many notes all sharing a stem all have varying combinations of articulations — all the staccato notes on one stem, all the tenuto ones on another, all the accent-staccato notes on yet another, etc.
