Elektron Musical Instruments

As a MD owner I am very interested in the UW upgrade offer.  I don't 
use MIDI too much other than syncing up the MD & MM in song mode and 
then recording it on my aw16g.  As far as loading the samples though 
MIDI or the new interface being designed, how or what program would 
you use from your computer to load them?  Sorry if this an obvious or 
basic question, but I want to find out if the UW will work for my 
particular way of making music.  Also are the samples tempo adjusted 
as you change the bpm in the MD?  Last question, are the samples like 
all of the other machines in the MD, just record them to a step and 
use parameter locks etc?  Thanks very much, -Scott
