Yamaha DTXpress/DTXplorer/DTXtreme

OK here's the deal.
I didn't want to do the factory reset.As I said, my program change 
device works. 
But as I wrote that I thought..'it works UNLESS I have been playing 
along with the internal songs'... If you press SHIFT/ MUTE the drums 
are muted.But, for some reason, it also keeps my program change device 
from working. WELL, low and behold, it was also keeping my PM-16 from 
getting thru. What kind of deal is that?
So I started getting the faintest sounds of PERCUSSION. I made the 
proper note number settings and I HAVE DRUMS!
BUT the only way they are loud enough is with the input slider set to 
MIC rather than LINE/TRIG, and the pot all the way up. I have set the 
voice volume in xpress to 127. I went into the Level menu in the 
PM-16.The voices from the pm-16 pads have just a little less  volume 
than the same voices from the xpress pads. Same type pads too.
AND contrary to what I remember from an earlier post, it remembers my 
patches. I have two set up now, 31, and 32.I turn it off, they come 
back!!! This is great.
To underneathheaven:That 84 or 83 in the display is a bank number and 
a patch number. Select a different patch number, say 5, making it 85. 
Try some different settings and see if they will save. The only 
downside is each group of patches needs its own set of different note 
numbers, if you want different sounds.
Any insight into the volume thing?? Anybody?? Please??
