Yamaha DTXpress/DTXplorer/DTXtreme

Hi all,

I've been reading this group for a few months, got my DTXpress III
just under 2 weeks ago, and I design electronics for a living, so I
have designed and built the "Magic Box" I've heard about.  It is more
of a bird's nest and needs a bit of tweaking, but it works.

It has two inputs and one output.  I have put a TP65 into each input
and taken the output into one Tom input and told the DTX it is really
a 3 zone snare.  Now I can hit one pad and get one sound and the other
pad and get another! It needs a tweak because I have made the
detection of the pad which drives the rim switch too sensitive so that
while it works fine off the rack, hitting the non-rim pad on the rack
triggers the rim sound on all but the gentlest of touches.  I will
just need to change a resistor, but it probably needs an adjustable
one becuase you would need the equivalent of a rejection adjustment,
but you cannot do it in the DTX box becuase it is too late by then.

Must go, drum practice time, then I am going out.

I will post more information when I have adjusted it and had time to
try it out a little more.

Keith.
