Don't Count the Ornaments In This Piece

I've tried to count the number or trills and mordents in this chorale prelude Christus, der uns selig macht by Georg Friedrich Kauffmann but lost it. It's one thing to perform them on a mechanical action organ but it's completely different thing to play them well on a plastic keyboard such as mine. How do you like it?

I'm playing this piece using Altenbruch sample set by Sonus Paradisi of Hauptwerk VPO. If you like my music making, you can support me on Patreon and get free organ CD's at https://www.patreon.com/secretsoforganplaying
