Yamaha DTXpress/DTXplorer/DTXtreme

I read somewhere else that a member of this group was developing a 
SYSEX editor for the dtxpress II and wondered if there had been any 
progress on this?

I searched the archive for "sysex" but didn't find anything useful 
or relevant.

Alternately, does anyone have the full specification for the 
dtxpress II sysex format (as I am a programmer and may consider 
writing my own).

Regards,
Gary Menzel

Hi Gary,

Welcome to the forum. Peter, aka the_kin_doc, in Australia finished 
the text editor and made it available for download at 
www.valwahjukes.com. 

Ed

Thanks Ed,
 
I have downloaded that to my laptop now.  The doco says it will work
"offline" (ie. Without a midi connection) but I get an error (invalid
device ID).
 
I do need it to work without being connected - any tips/ideas ?

GAry,

It's been a while since I looked at the code but I suspect that the 
program looks for MIDI interfaces and expects to find at least 1, in 
which case it's sloppy error trapping on my part.  If that is the 
problem the quick fix would be to load something like MIDI Yoke 
which will give you a few "software" MIDI interfaces.  You can find 
it at :-

Hope this helps.

Cheers, 

Peter

Excellent - that solved the problem.  I did have the Yamaha XG WDM
SoftSynth installed as an output - so it must have been looking for an
input.
 
BTW - in waiting around for downloads and suchlike - I noticed the
format of the SYSEX files you have seems to be a tiny bit different from
the information I found on the group site (on first glance the name of a
kit is 12 [not 8] bytes long).  Are there any other changes that you
know of?

From memory, that's the biggest mistake in the Yamaha spec.  The 
others that I can think of off the top of my head are:

The size of the System sysex is wrongly specified (1 byte short I 
think)

The definitions of some of their data types OB64 etc. are wrong.

The parameter change sysex messages for altering the tempo setting 
for a kit don't work (due to a bug in the unit itself).
