Drum Tracks

Hi All,
I’m using ez drummer in LE7, it works fine up to a point. I can drag the toontrack midi files from the ez drummer plug-in onto my drum track with no problem. But when I drag midi files that weren’t created by toontrack from the plug-in into cubase they automatically default to a new GM drum track. From there I can drag them to the ez drummer track no problem but it’s just the initial not being able to get them straight to the track I want thats confusing me! Any ideas anyone? Thanks in advance,
