Yamaha DTXpress/DTXplorer/DTXtreme

Hey all,

I'm new to this group, my apologies if I'm going over stuff that was 
covered eons ago.  I'm also searching through the archives.  I have a bunch 
of problems, but I'm starting with this one.  I have a DTXpress, mostly as 
a trigger and programming tool for my sequencer.  So, it's MIDI'd into a 
MOTU MIDIExpress (lots of permutations of "express" in my studio).  It 
seems that the DTX sends out a LOT of MIDI data that creates some problems 
with my interface.  It looks almost like beat clock, a regular pulse of 
data that goes to all channels.  It's not a MIDI loop, MIDI through if off 
(it's the only device on that channel).  Also, this is with the computer 
not even on, so it's not a sequencer thing.  I've looked for something that 
would be doing this with no luck.  Any ideas?  I'll be asking more 
questions in the next few weeks I'm sure.  I know a teensy bit about 
computers and music, so I'll repay the favor if I can.

Thanks, and good to meet y'all,

TCB
