It’s maddeningly frustrating to have delay tails continuing for a good 1-2 minutes after song is stopped. This appears to be common on all delay VST plugins I’ve experimented with. This is also a problem that just randomly started happening as I can pull up 9 other older projects and they do not have the problem with those same VST plugins.
It’s almost impossible to continue working this way without some kind of auto-kill for all plugins when the song is stopped or to go into the mastered file manually and edit/mute the tails at the end of the song.
There have been other users with this problem, but I’ve yet to find a viable answer. There is a subject from 2016 on this problem, apparently I can’t post link to it, but it’s titled
" How to Prevent Delay FX Continuing to Sound on Song Stop"
