There does not appear to be any progress on my earlier notification to support.
I am using the latest update, and have done so since 2010 as well as the new version every year.

I will be more explicit so you can see what I mean.

Start new song, start new style (Test1)
In stylemaker bass section
8 beat program C (2 beats) E (3rd above 2 beats), same next bar.
save with no masks and weight of 5

that is only one 8 beat riff.

4 beat program beat 1 C, beat 2 B, beat 3 D, beat 4 Db.
Save with a weight of 9 (always) and next inteval "up 2nd"

in the song set key to C
set 1 chord for each bar (C, D, E, F, G, A, B, C)
that is 8 bars

Open notation, set to bass and generate.

As you can see, when it does not recognise a 2nd it defaults to the first 2 notes of the 8 beat riff (this is the default) and if you set a different Key that it happens at different points.
