Yamaha DTXpress/DTXplorer/DTXtreme

A BIG hello to all you faithful disciples of the DTXpress. I just 
rejoined the group, as I know that this group has the BEST source of 
information on the subject. So many learned Guru's out there with a 
sea of experiences....
As expected, I also converted to Electronic Drumming, after bearing 
the "scars" of Acoustic drills of drumming,  and literally love my 
new acquired "faith".

I have noticed that many of you are using a Roland KC-500 for your 
amplification requirements, and have given favourable comments on 
this amp.

I just acquired a KC-500, and wanted to ask some questions. First of 
all, I noticed that  VOLUME levels for each kit in the DTxpress needs 
to be increased quite a lot, in order for the KC-500 to expound on 
the amplification. I raised the volume levels of each pad, e.g kick, 
snare, cymbals, toms close to 100. Then also, raised the overall 
volume under (UTL), in order get decent amplification out of the KC, 
without cranking its volume levels.

Could you please help me, in figuring out decent volume settings for 
each pad and overall volume settings, in order to prevent the KC-500 
volume cranked up all the way just to hear the drums.
