Yamaha DTXpress/DTXplorer/DTXtreme

Glen,
 
You can look in the photo gallery of this site and see what the inside of
the PCY65S looks like. The rim switch is actually a pair of split ribbons
that run along the edge of the plastic wedge. Historically, starting with
the PCY80S and then with the PCY65S, rim ribbon switch have been a problem
area. I have an assortment of the PCY65/65S/80S. The PCY80S are the most
troublesome in regards to the ribbon rim switch. If I strike the edge of the
pad with the stick nearly parallel with the pad surface 9 times out 10,
unless it is a glancing blow the cymbal will choke un-intentually. If I
strike the edge at a sharper angle with the stick being 45 degrees from
parallel with the pad surface the edge will trigger properly 9 times out of
10.
 
The PCY65S have less of a problem with this as the edge design was changed
slightly. The problem with the rim switch is it is being used as a dual
purpose device, one as the edge switch to trigger the rim voice and secondly
as pressure sensor to detect if it is being held. It is that time delay that
in many cases is the problem. The time delay is not adjustable either. If a
brief contact is made with the ribbon switch it is interrpeted as a normal
strike and the rim voice is triggered. If the amount of contact time with
the rim switch is longer (i.e. it is physically being held) then it
interrpeted as a choke and the pad and rim voices are cut short. 
 
So, you may indeed have a bad PCY65S, but you may also find that in the end,
as with most edrum issues it comes down to technique.

That's probably exactly what it is, is a faulty rim switch.
