BWV 169.2 “Gott soll allein mein Herze haben”, mit Violin obligato

I wrote only the violin part (4. February 2023 - and in this score I forgot to put the asterisk by the indication * Violin on the top staff), J.S. Bach wrote everything else. Original recording by John Eliot Gardiner (obligato track added by me). This is part of an ongoing project to add obligato instrumental parts to all of Bach's continuo arias (those arias from his Cantatas which were written for continuo and voice alone without any additional obligato instruments). This movement isn't an aria, rather an arioso, with interspersed recitative.
My reason for doing this is to learn from Bach's compositions, to challenge myself and improve my skills. This is a draft which may be improved. There are over 60 such arias to work with. I've shared some other efforts on my blog at aah.zentral.zo...
A note about my "score scrolling" software which I've been developing for these videos: this is the first I've made where the score scrolls at 50 frames per second. Previous scrolling videos have used 25fps. Does it look smoother? A bit, I think. The audio syncing still needs some work. You may notice often the red bar isn't exactly at the sounding spot. This isn't due to the software not being able to sync, rather a question of where sync points should be placed. Right now the barlines are the main sync points, but the notes really should be the main sync points. So I'll be improving that.

Very nice addition. The scrolling is quite smooth. What did you use to write the program? Lilypond and libav?

Thank you. The app is written using Xojo xojo.com (with no external libraries). It processes normal PDF scores (here, exported from MuseScore 3)
