Yamaha DTXpress/DTXplorer/DTXtreme

Hi,

I use cakewalk pro audio 9 to record my dtxpress. At this point it 
works quite alright. Since I have a laptop, which mostly comes with 
inferior soundcards i use my dtxpress module as my 
output/soundsource, until I get a keyboard, which automatically 
brings around another soundsource I can use.
However: when I record my kit, cakewalk always tend to send message 
to dtxpress to use the "GM Standard1/2" kit, so during countdown my 
preferred kit changes to the just mentioned. Of course it ought to 
be because its "standard" and that it fits in a GM-way. Yet, I have 
programmed all the midi-note numbers on my preferred kit so it fits 
accordingly, and during recording I change to "my" kit, and it stays 
that way, and during playback also uses "my" kit.
My question is therefore how I can prevent cakewalk from altering my 
dtxpress display and not mess with my kit-preset. I could of course 
unplug MIDI-in, but then again...no.

Suggestions?

Regards,
Rick
