Yamaha DTXpress/DTXplorer/DTXtreme

Hi All,

Does anyone know if there is a SYSEX editor available for the 
DTXpress?  I'm just not real fond of all the menu hopping and button 
dwiddling need to set parameters on the our little beat box.

Also, I remember an older message asking for ideas for a new piece of 
software to use with the DTXpress.  Well, if a SYSEX editor doesn't 
already exist, this is my contribution to the list.  I have no idea 
how difficult it would be to write, but it would be nice if was more 
than just a data dump.  If it could identify each parameter and it's 
maximum and minimum values, plus show the "default" or "normal" 
value, that would be helpful when experimenting.  Using this in 
conjunction with DTXchange, the SYSEX loader, would be great.

By the way, if such a beast already exists, just point me in it's 
direction.

Thanks for your help,
jp
