I never used the chords sequencer on the BK-9 before.  I recently tried  both the chord loop and the chords sequencer.

Chord loop is nice, you can create a chord loop on the fly, however with the chords sequencer I thought that you can create a chords sequence, save it and then use it with a different style if you wanted too, but what I noticed is that when you load the previously saved chords sequence it will select the style that it was created with, even if you have a different style selected. 

Is there a way to apply the chord sequence to different styles or there is no option for that?

While I did the chords sequence recording, if I changed the variations those will also be saved to the chords sequence file.

Therefore, each chords sequence is created and applied to only one style, the style that it was created with?

I'm curious how some of you are using this feature, and what's the benefit instead of recording the whole thing as an SMF, if the chords sequence cannot be applied to a different style?
