YOu can format a dsdd disk as ibm with cross dos in workbench 2.x or greater.
 
Then use bars and pipes to record, make sure you have the record sysex option
set.
(Click on the input midi jack and set option  on.)
 
Then do the voice dump on your keyboard while you record it with bars and pipes.
then save the file to the ibm formated disk with the smerff accessory as a
standard midi file.
NOw load the midi file into an ibm sequencer, and give the load sysex voice
data on the keyboard, and play the sequence,  (click on the midi out jack
first, and make sure the play sysex option is on first.)
 
I think this might do the trick for you, but I do not have your equipment to
test it.
