Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,I just bought a DTXpress III kit and when recording a midi
track on chnnl.10 in Cubase SX, all works well except the cymbal
choke. While audible thru headphones & the module's stereo out,
the 'choke' is not being recorded in the Cubase sequencer midi track. 
I suppose it's a midi note number hangup, but I don't know too much
about midi programming.
Is their a value in the module or the Cubase sequencer I can change
to activate the cymbal choke effect for midi recording??

Thanks for any help.

James
