--I was playing back a sequence that I made from the drum editor on Cubase SL last night and realized that the hi-hat events weren't excactly as I planned. Even though I intended this particular part to play an open hihat, the sound came out as a closed hihat. But what's even more confusing was that just a measure earlier it was playing the open hi-hat as intended. In other parts, the open hihats would be closed or would sound like someone is messing with the FD-7 hi-hat controller (Vdrums) when I'm playing it. The open/close events for hihats aren't being rendered accurately throughout the whole song. What am I doing wrong?
I took the following steps in figuring out the problem, but to no avail:

(1) When I add an event on the drum editor, every event I enter with my mouse makes a sound right? Well, when I enter an event corresponding to the open hihat, it makes a closed hi-hat sound.

(2) So naturally, I go over to my vdrum to check the hi-hat pad only to find that the pad is playing a closed hi-hat sound even though the hi-hat pedal is not being stepped on.

Could it be that, at some point in the song, there is some kind of message being sent from Cubase to the TD-10 telling it that the hi-hat pedal is being pressed down?

--Also, another problem. When I start the midi playback from the beginning of the song, sometimes the first beat comes out delayed. What is that all about?

--Then finally, when I was experimenting with some effects, it automatically doubled up on my existing events at certain points of the song (e.g. the event, whether it be a snare or hihat, were doubled so when I try to erase it completely, I would have to click on it twice with the eraser cursor...am I getting this across correctly?)
