Yamaha DTXpress/DTXplorer/DTXtreme

Gianluca,

I'm surprised that no one has posted a reply before now. I can't 
troubleshoot with you in detail because I don't own a lot of the 
equipment that you are using. I can tell you that none of the 
problems that you're currently experiencing should be permanent. But 
I should warn you that live playing can make crosstalk worse, often 
requiring you to alter trigger settings that may have worked well in 
practice, and sometimes to find new strategies for physically 
isolating pads on the rack. 

From your note, I'm assuming on point (1) that you managed to find a 
specific rejection setting on the snare for the hi hat that allows 
you to hit both at the same time. Now (2)the snare double-triggers 
(like a flam). I'm a little baffled that it happens when you hit 
softly, since the risk of double-triggering increases with velocity, 
but you may have your snare's min. velocity set too low and your 
gain set too high in the trigger menu. Try setting the former at 30 
or higher and the latter at 65 or so; adjust as necessary. You may 
also have the sensitivity knob on the bottom of the snare turned too 
far clockwise. If so, turn it back halfway. If you want to increase 
your volume, use the voice menu, the volume parameter in the utility 
menu, your amp volume, or your headphone level. Pusing the trigger 
parameters too high can create all sorts of anomalies.

If (3) you get a cymbal crash when you play fills on your snare 
and/or tom pads, you have to increase rejection on that cymbal until 
it stops responding to other pads. General rejection may be all 
that's needed, but if you enter the trigger menu for various inputs, 
you can see whether hits on particular pads cause the crash to 
trigger. For instance, on the gain page for input three, if the 
crash cymbal's reading intrudes, you'll know at least one source of 
the vibration. If only one trigger, like #3, seems to be the cause 
of the cymbal's inappropriate crashing, then you can use specific 
rejection to correct it. If the problem is more general, then 
rejection per se would be the right approach. As I said before,  
keep your gain, min. vel., and sensitivity settings for all triggers 
at reasonable levels.
