I want to make a rhythmic cue for the drums cuing an instrument that has both a regular voice and a slash voice. The problem is that, whereas the regular voice shows ok as a rhythmic cue, the slash does not. I don’t know if this is a limitation or intended behavior, and if there’s a suggested way of doing this (I’m thinking of cueing a hidden instrument).
When cueing a pitched instrument on the drums I get better results but still somewhat inconsistent.
This is exactly what I would do if I were you.
I too had success with using a hidden treble staff cue instrument.
Counterintuitively, it’s better not to use a percussion instrument for this, but a treble staff pitched instrument. These are more flexible, e.g., you can change noteheads to slashes in the cue instrument, and they will reflect properly in the cue.
Hope that helped,
