Dave Smith Instruments SYNTHESIZERS

I would like to load a sysex file into my pek using midi-ox.
I know how to use midi-ox and system ex is turned on in my pek, but
the banks do not take.  

is there a guide that I am missing?  ive looked and cant find how..
thanks

well.. im using Bome's sendsx and I can read and write combo banks.
But, when I try to write program banks, all that happens is the
program name changes.  The sound the program makes is the same.
Hmm

nevermind... I just used my Mac OS X and it works great with sysex
libararian.

PCs do sux ;-)  

well.. in my case here
