Song Mode Sync

Hey, i am just starting with the song mode and I found a limit which i am sure has a solution… My Digitakt control a Digitone, Song mode activated on the Digitakt, it is all ok, but when i programm, in song mode on digitakt a sequence for playing only the 4 first trigs, then pass to another séquence, my Digitone read its full séquence, which is 16…
IS there a way for the changing of séquence to be instantly, following the digitakt, even if the séquence IS not finished playing ?
