cubase sx2 prob with step sequencer (i think)

ok i have this a1 synth playing a melody from step sequencer and 2 patterns r exchangin n looping and everything works nice, synth plays tru the whole tune. but when i export the whole track and listen to the wav i notice that the synth just stops playing after min and 29 secs.....and it shouldnt, it should go on tru whole 4 mins like it does when its played from cubase.....and i dont fukking know why ...tell me plz...

Try transforming the sequence into a midi track after that i shouldn't happen anymore...

I don't know why really!?

don't u have any more tracks playing 2 that same channel or instrument?... no other messages exept the notes 2 exchange tha patterns?

Also U can maybe grab the audio from the first part that plays right and then cut& paste forward~as a simple work-a-round!
