Summary: bug in score sorting w/legato instruments (negative p3)
Initial Comment:
I found a bug 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.
Thanks,
Aaron Krister Johnson
