Elektron Musical Instruments

Hi everyone.

So heres a question for ya'll.  I was in song mode on my 
monomachine. Not sure what happened- I think I had it stopped 
and was switching patterns or something.  The synth froze and 
when I powered back up, the memory had reset.  My assumption 
is that all previous song, pattern and kit data are gone but if 
anyone knows a way to get them back, I'd really, really love to 
hear all about it.

Best,

Brian
