The is a short note played but no TRIG is lit how do I kill it?

with fire

kill it with fire

Bug spray of course.
You could try:
In live record mode, function+clear, hold till the tracer passes the problem note.

Thanks Guy! A teaser seem to be the best remedy…

@StinkyBeat sounded like a good idea but nadaa… I even placed notes in the area and deleted normally and with your method… gives new meaning to a “ghost hit”
