An usual issue for loop play too.

I really like that for Ardour2 HD recording, the audio recordings are
some frames behind.
IMO there's no good or bad way to handle this. Music shouldn't be cut if
possible and the behaviour of what sequencer ever shouldn't be copied.
There's no master rule for the most best behaviour, resp. a note should
be played by the first region, overlapping to the following region. If
the "following" region is played only, than the 'syncopation' shouldn't
be played, the note should be missing. (Ok, for loop play it would be
nice to hear the 'syncopated' note too). A sequencer should have the
same behaviour as a tape ;). This isn't really possible, since a tape
can cut a played note in the middle, but a MIDI event would need to
become two events, which is unnatural.

IMO there's no need to think about unnatural behaviour. For 'play' the
note should be played by the first region (clip, segment) and lap over
the next region (clip, segment), for loop play it would be nice to start
the 'syncopated' note, at beat 1 of the following region, assumed this
region is the first for loop play.
