Hmm... Not sure what I am doing wrong can not get it to work right. Can somebody tell me if what I am trying to do is possible at all.
Example:

First 4 Bars - Style ABC
Bars 5-8 Change of Style DEF

Then I select first 4 bars (ABC) do "Copy From...To" All 5 things on the right are checked (copy chords, Copy Bar Settings, etc.) Then I copy bars(inserting) to bar 9. Clicking "Generate and Play.
Bars 9-12 play DEF, not ABC...

A bit confused here.

If I copy not "just" chords, but complete line, why is it playing DEF style instead of ABC?

Kindly help.
Thank you.
