Can you please give us more detail on how you are making your MIDI patterns, or where they are from?
I have seen synths map to different keys, so I can get into trouble blindly inserting/moving MIDI data around. Drum maps can vary from set to set. Is it possible that "crash" was intended to be a different (intended) MIDI note, but is just on the wrong note (drum)? (your PRV may not be displaying the proper drum map?)
Edit: Just in case the above may be possible. Here is a
thread with AD drum maps you may find helpful.
