The 're-trigger' notes you hear at ~ 1:13, 4:50, 4:55, 4:57, 5:03 and 6:46 has been an issue the PA series have had since the PA50.
And that is what drives me crazy. Why on earth no one at Korg manage to find a way to prevent this happening?! All the others, except for Casio I thought, do not have this issue.
This thing is particularly annoying with ballads or another slow tempo styles.
