Some months ago, “pianoleo” (a member) gave me the link to a police that allowed me to write metric conversions like “quaver of a quintolet = semi-quaver from a triolet”. I can’t find the procedure again and would be very thankful to whom who could give me the path to be followed for.
Dan Kreider recommended the Metrico font in a previous thread of yours, here: Tempo equations
More recently Dan Kreider’s developed the MusGlyphs font, which does the same thing as Metrico and plenty more. See MusGlyphs - Notation Central
Thank you very much, indeed!
