Les éditions modernes des répertoires anciens, étant elles-mêmes des interprétations, peuvent très facilement induire chez le musicien des défauts stylistiques.

I'm not so convinced that a competent continuo player is always better off reading from a score than from an original figured bass part. My own experience is that one listens more carefully and integrates better in an ensemble—that is, functions less as an "accompanist" (or coach/accompanist) in the modern sense—when reading from such a part. Clearly the character of one's continuo realization will be different when one responds to what one hears other instruments do than when one manufactures the part on the basis of one's reading and analysis of the full score.
