Yes, after watching the video, it's clear to me that there's something wrong there. In fact, the issue seems to be much simpler: loop tracks do not seem to respond to Style changes through F5

To replicate:
1. New Song > load any style with loops
2. at bar 5 > F5 > Change to any all realtracks style.
3. Press play > The loop tracks will ignore the style change at bar 5.

Or:
1. New Song > load any all realtracks style.
2. at bar 5 > F5 > Change to any style with loops.
3. Press play > The loop tracks will be ignored at bar 5.

Good job, swingbabymix wink
