I am quite unfamiliar with sysex, but have been using midi-ox for 
saving my data with my MD.  I have only been saving one to two 
kits+patterns at a time... when my MD sends more messages than four 
or so, the bits recieved by midi-ox start escalating extremely fast.  
Is this normal?  Does anyone sysex dump songs?  It seems that it 
would take me too long to wait for my computer to recognize... or 
load.. or whatever it is that it is doing.  I played with the buffer 
settings (a lot), but that didn't help.  What should I have it set 
at?  I also shut off the delay also.  I guess that I can just keep 
saving only small files... but it seems inefficient.  Now my real 
problem came about when I tried to upgrade my OS.  It took midi-ox 
half an hour to load the sysex file... is that normal?  Well anyhow, 
I tried many times to send it to my machinedrum like the instructions 
tell me... but my MD isn't responding.  The LED's don't light up like 
they are suppose to.  The screen says that it is waiting for the MIDI 
upgrade and everything is hooked up properly.  Midi-ox is sending the 
sysex and it takes ten minutes... but nothing.  I am extremely 
frustrated and would appreciate any help.  Thank you for reading my 
long winded post.
peace.
