phooka, thanks for reporting this. It seems to be the result of a complex interplay between the Navigator and Grid Pie
Basically, you are able to jump around inside patterns with continuous playback.
However, the first position is special since it will (when you are pressing the button just when exiting the first block) jump to the last line of the previous pattern
This is then picked up by grid pie, and will cause it to switch to that pattern - which, in itself, is the way it’s supposed to work. But in this case, isn’t what we want.
I have to think about a way to avoid this - probably a hackaround which will simply ignore pattern-switching when at the very end.
As for the loop button being highlighted, this is just the transport telling duplex that the pattern is looped (the grid pie pattern is always looped, but using a pattern sequence loop), and nothing to worry about.
