Even the oldest styles work fine on the EA7.
The BK, G70, G1000, E, all play fine.
All load fine.
Yes the EA7 plays 4 fills, it drops fill2 up and1 down..
I never miss the 2 less.
If the older style uses less than 4 intros, endings, or variations, the EA7 will doulble up, it seems to add another tone to the duplicate ..
There will be no empty locations.
The best news, they all sound better on the EA7.
