I just got my machindrum.  It's so lovely.  Is the upgrade to the 
beta worth it?  Or is it full of bugs?

Also, I'd love to sync my machinedrum to my virus and later use the 
midimachines.  But currently, when I have my midi out of my 
machinedrum to the midi in of my virus, and i try to sync them, the 
md sends out the clock data.. but for some reason, when i press the 
drum trigger keys on the md, it also triggers notes on my virus.  How 
do I prevent this?  And why is this happening?  This is preventing me 
from syncing the two machines together, because I cant stop the note 
triggers.
