Yamaha DTXpress/DTXplorer/DTXtreme

Hi

I just received my DTXPress IV Special today and I'm a bit disappointed 
with the volume.

I play with my phones and I have to turn the overall volume to the max 
(the kit is still not too loud). It's not because of the phones, they 
work well.

When I listen to a preset song, the prerecorded drums are very loud(!), 
much louder as when I play. Is there a way to have the volume as loud 
as the recorded drum songs?

Hope you know what I mean... Thanks!
