unexpected double tempo

[pdxdjazz]

I created a song that switches from 3/4 time to 6/8 time in the middle. Technically a bar in 3/4 and a bar in 6/8 should have the same length. But when the 6/8 part begins the bars are played twice as fast as expected.

Experiment with different player styles.
You'll find the artifact you describe occurs in some styles eg. Swing, Ballad-Swing (not Ballad-Even/Melodic)
but not in others eg. Bossa, Latin, Pop (except Shuffle)
Interesting that Latin/swing behaves like the swing styles (even in the Latin section)
