Yamaha DTXpress/DTXplorer/DTXtreme

Hi, 

I am Can, from Turkey/�stanbul. I am beginer in drumming and I am hapy to find your group. Too many good ideas and lots of experiance... Thanks
I use DTXplorer kit with 3 zone snare sins 2 months.
My Roland HD-1 drum tutor yesterday arrived, I knew from your experiances that this tutor works with DTXplorer kit if one can make some arrangements.
 As far as I know, MIDI notes numbers of DTXplorer kit and HD1 drum Tutor are not same. Thus only HH works correctly.
Would you please explaine me how can I make this MIDI notes numbers changements ( I hope it is possible)

Thank you 

Can
