Hi antman,

I've noticed that certain cymbals have a tendency to choke 
themselves as well. The inexpensive Pintech TC series was notorious 
for that in my experience. But self-choking seems to be a hazard 
mainly of stereo cymbals with their choke function. I remember that 
it would happen when I hit the bow and then inadvertently hit the 
rim or lay the stick on the rim for a split second. When you're 
wailing away on e-drums, especially live, it's really hard to 
maintain proper technique and keep bow and rim separate on a stereo 
cymbal, which isn't an issue with acoustic drums. The rim switch 
functions as an on/off toggle; it's relatively easy to activate.

About the snare, a couple of things spring to mind. The first is 
that the self-rejection setting may be too high. Try lowering it one 
notch at a time until you can hit the snare multiple times in rapid 
succession without dropping out. Self-rejection, like the other 
forms of rejection in Yamaha's arsenal, actually silences the 
trigger for a micro-second, based on the force of a hit, to prevent 
it from double triggering; it should be as low as possible to get 
the job done. Keep your gain in the trigger menu and the sensitivity 
knob on the underside of the drum at moderate levels, too, so that 
you don't have to crank self-rejection to counteract their effect.  
Furthermore, playing live creates all sorts of vibrations--
opportunities for crosstalk--along the rack that probably don't 
occur when you're practicing at home; elevated rejection and 
specific rejection parameters for the snare in a live situation 
could cause it to shut down periodically, even if hit at a level 
above self-rejection's muting threshold. When you set pad type for 
an input in the trigger menu, settings are automatically adjusted, 
though these settings should be regarded a ballpark rather than 
gospel. Hope this helps a bit. It's basically a balancing act.
