Yamaha DTXpress/DTXplorer/DTXtreme

Or does Yamaha's DTXtreme have such a digital connection? I just 
looked and my Alesis DM Pro has digtal RCA connections.

It seems that a lot of equiptment these days are offering digital 
connectivity in their products. Even Gibson is making a Les Paul 
guitar with a digital output!

I just bought a Digital Optical cable to connect my Vox ToneLab 
guitar amp modeler and will try it next on my Alesis keyboard synth, 
and I was thinking it would have been cool to try it on the e-drums 
as well.
Though I'll do some experimenting in the future with the DM Pro.
