Tempo track display only goes to bar 153, that is true and we will fix it.
However you say “cursor” does not extent beyond bar 153 (if that’s what you say?), and that does not apply here. I can set the cursor wherever I want (say, bar 253) and set Part trigger for Part2 (if that’s what you mean?) w/o problems. What are you doing differently? Does this step-by-step procedure not apply in your place?
with cursor, i mean, the green vertikal line. i can’t set it in 3 of 4 songs after the tempotrack display line, and the 1 song is shorter than 5minutes.
i try the song from yesterday in an empty new project, and that works.
on weekend i have 3 more tracks over 6minutes to write in the existing project. i write every step on paper for finding the error.
try to edit the triggers of an existing song in the project and the error occur, i can’t set the vertical green (cursor) line after the visual end of the tempotrack line, which is by #151.
I made a short video of the fault.
