Yamaha DTXpress/DTXplorer/DTXtreme

I was planning on running them to the DTXpress brain, and then out to the 
keyboard, and then run my keyboard to the mixer, as well as running the 
outputs of the brain to the mixer. Can I use some triggers to fire the 
samples in the DTX brain, and at the same time have other triggers run 
through the DTX and out to fire the samples in the synth, simultaneously?
