Easy Search-Replace for 1 shape in a 7-shape shape-note score?
I use the tool for replacing the standard noteheads with shape notes A LOT lately in my current project. However, I would like to keep the standard notehead for shape 5 (SO, or SOL). The tilted oval shape is wider, with thicker lines along the flattened "sides," more aesthetic, and distincter than the small faint circular shape rendered by the user tool. I want to keep the clefs and other symbols in the standard notation typeface (nwc2stada) as well. So, I've been running the shape note tool, then manually replacing all the shape 5 noteheads. It is a wearisome process and I'm afraid I will overlook some notes.
How would I go about creating a tool to replace all instances of one shape (shape 5) with the standard shape noteheads? This is possible, yes?
At some point in the future, I would also like to make alterations to all of those 7-shape noteheads, (as well as to other symbols such as the "flags" for eighth, sixteenth notes, etc.) but I believe I recall reading somewhere in the forum that those shapes aren't produced like other fonts and a font editor would not be of use?
***The line thickness of the shaped noteheads in the NWC2MusikDingsSans metric is actually what would be satisfying for my present need, but only with the standard notehead shape substituted for SOL (shape 5), while at the same time keeping the NWC2STADA clefs, time sigs and other accompanying symbols. Wish there were options for mix and match along this line. There are parts I want to use from one set, without giving up what is best found in another.
Are there any users knowlegable in this area that can point me to resources for creating a new set of symbols, or symbol fonts that the noteworthy program can be made to recognize?
