Cubasis 3 and Roland TD-17 midi issue

When i record the TD-17 mini via usb, the hi-hat and the cymbals are not recorded properly some notes are missing.
Also when i turn the “local off” at the TD 17 and route the midi via midi thru the same issue. Also the midi thru has more delay as with Cubasis 2
It seems that Cubasis can not handle the fast notes from the Roland drum. With Cubasis 2 it works fine.
