Arpegio intermittant
I decided to test out the arpeggio with that Chopin Etude, and found that it will roll the chords sometimes, and other times not. I attached the file. Is there a way to get an arpeggio to play across both hands? I mean to start with the lowest note in the left hand first and continue rolling up to the top note in the right hand. This is symbolized by an unbroken, arpeggio line across both staffs.
Also, I read that slurs are supposed to be interpreted now, but I haven't noticed a change in playback.

I suppose what should happen is that in order to enter a arpeggio across two staffs the user should enter an arpeggio for both staffs individually, then double click the top one and drag it down to the bottom, similar to how cross staff bar lines work. That way it would be consistent.

Good suggestion

I have not been able to lengthen any squiggly arpeggio notation at all.

This feature has not been implemented yet. The post above was just my suggestion for how to make the user interface for this feature.
The change between slurred notes and regular notes it very subtle. Regular notes are played for 85% of their full length, slurred notes and tenuto notes are played for 100% of their full length.
I am preparing some midi event output to prove that MDMilford's suspicion was indeed correct. More to follow soon.

I keep forgetting the version factor!
In 0.9.4, it is true that some arpeggios are not played as they should be. This shows upin the output midi file (see ChopinEtude11-0.9.4.mid.jpg attached). But I just tried it on r1712, and all arpeggios are handled as they should be. (See ChopinEtude11-r1712.mid.jpg.)
I still have some niggling thoughts:
1. An offset of 15 ticks (that's equivalent to a 32nd note) between the notes in an arpeggio seems a bit excessive. My experience is that an offset 8 ticks or even 5 is sufficient to create the effect in the kind of tempi that arpeggios are usually employed.
2. Shouldn't the duration of the notes in the arpeggiated chord be reduced according to when they are played? In MDMilford's example, every note still get its full 60 ticks, lasting beyond itsdue except for the first note of the chord.
3. Why all the note events are off by 59 ticks?
4. What's going on with those 0 duration 0 velocity note from r1712?

for number 4 at least, I think I have a guess In MIDI, a note on event of 0 velocity is sometimes used as a note-off event. Without looking at the actual midi messages (hex code), though I don't know.
Maybe in the future there will be a way to fine-tune the arpeggio--how many ticks between notes, and whether to use a squiggly line or a vertical slur. Also, some music has a grace note/arpeggio combination (just in case I haven't opened enough cans of worms). :-)

One correction first: The results I cited before was from r1723. I have no idea why I put down r1712. Sorry.
Now about the 0 duration 0 velocity notes: If the intension is to use them as note-off events, we would see them showing up regularily througout the file rather than just a few stragglers here and there. So although it's possible, I think it's unlikely.

Now I know why I said r1712 when I actually was talking about r1723.

MS does use 0-velocity noteons as noteoffs. You have my apology in my long post on midi files in the bug report sextion.
In reply to You were right by yingdat
No apology necessary. It was just a random guess on my part. :-)

The durations of the notes are indeed adjusted! It's the velocities of the notes that remain 60 throughout.
Mea culpa.
In the third chord of the 2nd measure (not counting the pick-up), on the right-hand part, is that A and Ab at the same time?
In reply to An clarification please, MDMilford by yingdat
Yes, that is indeed an A and an A-flat at the same time. I made another post about this issue. And how chords of this type could be made clearer. You can read that post here: http://musescore.org/en/node/1333
