I just added a cool drum part to my Studio One Producer and used AAA the part went on far after the midi data was done on the drum track but on the next music jam I layed down the drum track I layed down only lasted about 8 bars after the midi info on the screen. Why would that be and how I know how to duplicate one or the other ? Also how can I hear drums if there is no midi data on the track info while it runs thru the bars ?
