Yamaha DTXpress/DTXplorer/DTXtreme

Hi all!
Last week I asked for help because I had a concert..well, not 
everything went good, but I think it can only improve, because after 
a life on an acustic drum I think I need some time to practise and 
acquiring experience..
Well, as I told last week, I had some problem on snare pad, because 
some hits were missing and rimshot was delayed, etc. Well, I resolved 
my problems removing V2 layer on snare and rim pad..I don't know why, 
but it seems that dual layer was a problem, some hits on rim were 
captured by snare too, and I could hear some undesired hits!!
Using a single sound for both snare1 and snare2 (#74, I remember), 
and another sound for snare, I resolved that problem..
Main problem was VOLUME, anyway..I mean..after 25 minutes I couldn't 
hear what I was playing!!! my bass player looked in my eyes, I tried 
on concentrating on what he was playing, but..wow, rhythm was all 
wrong!!!! I was forced to use headphones and raise dtxpress volume on 
them, and finally I could hear my music..wow, what a bad sensation...
external sound was ok, but probably my ears were "tired" after 20 
minutes, and volume, which was good during check sound, was too loud 
with crow..well, it could be a disaster!!!:)
