While there were issues with bouncing automation and needing things selected, up until Ipswich if you had a MIDI track using the track based arpeggiator (in the inspector panel) and you right clicked and chose bounce to clip, the MIDI would become the arpeggated version.  That doesn't seem to work after today's update.
 
Steps:
Create empty project
Add MIDI track
In piano roll add one long 4 bar note at C3
Open track inspector and turn on arpeggiator with default settings (1/16 notes 2 octaves, forward)
select clip, right click, bounce to clip.
 
Result: nothing changes
 
Expected: single MIDI note would expand into two rows of MIDI notes 1/16 notes each an octave apart.
 
I tried this with X3 and it still works (just in case it was something with my computer).  It did work up till the H release as well.
 
Is there something new I'm missing to make this work now?
 
Update, Sept 24, 2015:  This was fixed in the Ipswich quick fix documented here

Hmm wonder now it behaves when using real time synth recording...

Using the steps in your post, I am able to confirm that bouncing MIDI clip with arpeggiator is broken in Ipswich.  Rolled back to Hopkinton and bouncing works as expected.

So can it be played out to another MIDI track as if it were Audio???

Doktor A..
I don't see in the ezine anywhere that we can re record MIDI as we would audio...
I'm gonna try when I get home.. I promise..
Then I'll update.

MIDI doesn't appear to be routable the same as audio, yet (I was under the impression that was still coming soon).  You could already record MIDI out from a synth/vsti that outputs MIDI.  But I can't take a MIDI track and send it to another MIDI track (with the Arp) directly.
 
 

If you send the MIDI track with the arp to Piz's midiOUT VSTi ( http://www.thepiz.org/plugins/ ) and enable record on it's MIDI channel you can get the results of the arp. 
 
That seems to work better than it did in Hopkinton.  In Hopkinton that using the VSTI as an intermediate required selecting the track with the arp and using a virtual MIDI cable.  Now you seem to be able to record the MIDI out directly, though I may just be remembering how it worked wrong.  I'm not interested in rolling back to test it.
 
Edit: Nope, spoke too soon.  Still some oddness with not being able to direct a MIDI track to None.  There does seem to be changes here, but it's not quite usable yet.

It does appear the function got messed up. In the interim, to capture the result of the arp try using a virtual MIDI cable such as LooopBe1 or LoopMIDI, route the output of the track with the arp to another MIDI track and record it.

I can confirm you can't bounce the MIDI track and end up with the arpeggiated data.
