Yamaha DTXpress/DTXplorer/DTXtreme

I just can't believe that it doesn't have a MIDI In port.  I know that 
Yamahamer over on the DTXPerience boards fought to keep the feature 
in, but I'm guessing it was cut so that they could keep costs down by 
using a case similar to the DTXplorer module.  Big mistake in my 
book.  How can it be considered a serious mid-level setup without the 
capability of using it with any outboard sequencer.

I'm glad I got a DTX III that works well standalone and with Sonar.
