Yamaha DTXpress/DTXplorer/DTXtreme

Hello,

I have a problem ! 8-)

I have a sound blaster live 1024 and i don't understand why i don't 
hear dtxpress sound via a midi connexion.
I think it's a configuration problem both sound blaster live and also 
dtxpress. I use a midi cable who have connected to a 15-din sound 
card (Gameport/MIDI).

What is the configuration in windows and sound blaster ?

thank for your help !
