Hi all,

Greetings from the road between Lexington and Louisville KY.

I found a bug yesterday in CVS version dated from the 14th. Score sorting fails with legato (negative p3).

I will send an example score and score.srt once I'm on my regular laptop (i.e. when I'm home)

Ok,

As promised, I'm going to illustrate the bug I found with a sample legato instrument score that uses the negative p3 trick to indicate a legato note which is to be tied to the next note event from the same instrument. Here's the input score:


t 0 120 
i201.0 0.000 .5  0.66  1  0.5  1 
i202.0 0.000 .5  0.66  1  0.5  1  1 .5 .6 8000
i10.0 1.5   -.5  0.66  261.62557  0.5  1  0.8
i10.0 2     -.5  0.66  391.26571  0.5  1  0.8
i10.0 2.5    .5  0.66  357.79083  0.5  1  0.8
i10.0 4     -.5  0.66  305.95299  0.5  1  0.8
i10.0 4.5   -.5  0.66  327.17991  0.5  1  0.8
i10.0 5      .5  0.66  327.17991  0.5  1  0.8

The results of the command 'scsort < legatotest.sco' are:

w 0 120
i 201.0 0.000000 0.000000 0.500000 0.250000 0.66 1 0.5 1
i 202.0 0.000000 0.000000 0.500000 0.250000 0.66 1 0.5 1 1 .5 .6 8000
i 10.0 1.500000 0.750000 -0.500000 -0.250000 0.66 261.62557 0.5 1 0.8
i 10.0 2.500000 1.250000 0.500000 0.250000 0.66 357.79083 0.5 1 0.8
i 10.0 2.000000 1.000000 -0.500000 -0.250000 0.66 391.26571 0.5 1 0.8
i 10.0 4.000000 2.000000 -0.500000 -0.250000 0.66 305.95299 0.5 1 0.8
i 10.0 5.000000 2.500000 0.500000 0.250000 0.66 327.17991 0.5 1 0.8
i 10.0 4.500000 2.250000 -0.500000 -0.250000 0.66 327.17991 0.5 1 0.8

As you can see, the p2 (event onset) times are not correctly sorted in order, and the audible result is screwed up big time. For example the event that falls on 2.5 beats comes before the one on 2 beats....what's going on here? I don't know why, but this is only something I've noticed in the CVS version I compiled on the 14th of July.

Can anyone else confirm strange behavior with any legato instruments and score sorting?

Thanks,
AKJ

Fixed in CVS.  The mystery to me is how the previous sorting worked in thi
sarea as I did not find any reference to negative p3, a feature I have
never used

Thanks, John. I'm downloading and testing it now. If I find anymore problems, I'll give a holler.

There were some additions to the sorting that John did earlier last month. This is why we need testers and super-users like yourself. Thanks.

It's funny, b/c I assume, w/o rigorous testing, that it had to do with negative p3 use, but in fact it was just plain old broken sorting.....glad I caught it, glad it's fixed!

Hi All,

Is this bug still happening?  I noticed the bug in the bug tracker was
closed as "fixed":

Hi Steven,

Yes, as far as I know, it is still a bug. Should I repost it as a bug in the sourceforge interface, or is John ffitch listening? :)

Things are working in 5.12.1 as expected in my experience. The problem seems to be with code that has changed recently in CVS. Victor L. mentioned some work on sorting code was done recently, so it seems natural to assume that therein lies the culprit.

I would recommend anyone who doesn't want any headaches with unexplained behavior due to score sorting to avoid using CVS code until this is truly fixed!
