Hi, I'm editing a score for a frame drum called Brazilian Pandeiro, which has many specific timbres. A common representation for those sounds uses particular note heads: Missing note heads for some high-pitched sounds of "platinelas" and normal head between parenthesis for a kind of muffled bass sound. With Musescore I've found a way to write the missing note heads, but there is no option for the normal note head between parenthesis.
I have produced an example using Lilypond software (file attached, see the first note of measures), but would apreciate if it was possible to write this with Musescore. Whould it be possible to add an option for such a note head "normal head between parenthesis"? Can I do this myself somehow? Thanks
