Yamaha DTXpress/DTXplorer/DTXtreme

Still battling with this business of the metronome/click getting 
recorded along with external midi user song data - but I have found a 
few things out about the  business - posted here for info:

1) There are apparently different levels of DTXpressII firmware in 
use, as an upgraded kit in Yamaha UK's tech support doesnt suffer 
from this effect (using the same Factory default reset settings) 
whereas mine does. Apparently the only way to tell if you're up to 
date, is to check the lables on the chips.

2) After pressing Record you get the click in the first 2 bar lead-
in, - If you're careful and hit hit the Click button just once, 
within this two bars - the click doesnt stop, but it will as soon as 
the count-in is over and the recording begins, - so it doesnt get 
recorded anyway.

I still havn't managed to synchronise recording starts yet - but with 
practice, Im getting better at pushing the buttons at the right time, 
so my 1 bar repeated patterns are sounding better.

Anyone know what format the user song data is stored in, in the 
memory map when its upladed using the BulkDump? - I'd like to write a 
translator to load midi files in directly without recording.
