This is another check and comes after Ive come to my wits end on my keyboard. At the end of the video where you have the walk going from D to A between walks the bass looks like what is an octave with another note, but I cannot replicate the sound exactly
but anyway what I saw was
D-E-F-G-A
C-G-C
Db-'Ab or Fb'-Db
and those limes loop until the song finishes
Are those what I thought I saw/heard, or did I miss something?
