I'm activating the Tempo Controller while a song is playing, it does well until the next queued songs comes, it automatically stops. Despite being checked, I have to double click the Tempo Control to actualize, and it works again.
I noticed that when I skips songs, go to the next one or precedent one, it is still on, but when I do not interact with MusicBee and it rolls automatically, it is not "on" despite visually being checked and etc.
