Yamaha DTXpress/DTXplorer/DTXtreme

OGD,

You are absolutely right.  I looked at page 12 of the reference manual
but didn't spot the note about putting the HH pedal into the kick
input.  I have tried it on my kit and it works!  There is clearly some
different electronics on that input to allow its use in this way.

So, the solution, ddindublin, is to plug your extra HH pedal into the
kick pad input, input 1.  You then need to put the KP65 pad into a
different input (probably 9/10 because the others will probably be in
use, but you will need a mono to stereo splitter for that).  Then go
to trigger edit (SHIFT+TRIGGER) and select pad 1.  The last option for
"TRIG IN" is HH Controller - it cannot be set to this on the other inputs.

I have tried this on my DTXpress III and it works.

Keith.
