That's quite strange.
Could you email me, privately, the code that produces those values?

I've always had the theoretical goal in MIDI::Simple and elsewhere that it
should not be possible to produce notes at negative start-times or with
negative durations.  But I've not built terribly many checks to keep it
from happening, particularly in the case of altering an existing MIDI
track/score.
