Hello,
I often work with French baroque music, and unfortunately Dorico does not offer all the flexibility needed for this type of continuo.
As a result, I never use the ‘built-in’ figured bass, very inadéquate.
I can only invite you to use the Go-Figure font developed by BenWiggy, a member of this forum.
Go-Figure is a revision of Figurato, which hasn’t worked very well in Dorico since version 4 of the software.
If you search « Gofigure » on this forum, you will find many thread about.
