Analogue-sequencer

I've been messing around with a lot of step sequencers recently and
the P3 looks like it might be the king of this hill.  The manual is a
little dense though so I'm hoping I can inflict my laziness on you and
ask a couple of questions.  Can the p3:

1. Play sequences of odd length?  Alongside even-bar sequences?

2. Play sequences in backward, reverse, alternating or random order? 
Can different sequences play in different orders simultaneously?

3. Can one sequence influence the playback of another?  Retrigger it
or make it jump around in play order?

4. Switch sequences in mid-sequence or only on sequence boundaries?

Apologies in advance for the lack of RTFM.
