I recall that you were asked:
Could you please outline what the starting style is and what style you change to later on.
and your reply was
Thanks for your proposal, but this happens whatever the styles
Unfortunately, only now you named two specific styles, one of which has tempo of double the other (260 BPM vs 130 BPM).
If you had answered the original question, this might have been resolved much sooner.
What happens if you choose two styles with same or very similar recommended tempos? Does the Style change then apply at the desired bar correctly?
