Yamaha DTXpress/DTXplorer/DTXtreme

Hi,

I'm new here, but was hoping to get a little help.

I have tried everything to get a decent midi recording of the 
DTXpress into Sonar.

Path:

DTXpress II --> M-Audio Midisport Uno midi to usb interface --> DAW

and

DTXpress II --> M-Audio Midisport Uno midi to usb interface --> midi-
ox / Yoke -->DAW (Sonar)

When looking at the input signal in midi-ox, It read "unknown"... no 
channel or note info regardless of what drums I hit.

I did get it to recognize the pad once...then back to "Unknown". I 
have tried filters, midi on , midi off info...timing, merge, 
channels...I don't know.

I can play a song from the DTXpress sequencer and capture it in 
Sonar. It will trigger whatever soft synth I choose. But I can't get 
the pads to transmit a recognized midi signal. 

I can trigger from Oxygen 8 keyboard, DD55 pads and even my old M1. 
All through the UNO. 

I have gone through the Manual and Reference guide all no help.

What am I missing?

Thanks,

Nick
