Elektron Musical Instruments

Hi, I am considering buying the M.D. to use it when d.j.ing, does any 
body have experience with this subject. I play agressive techno with 
a house influence and want to try mixing out of vinyl into M.D. and 
back to viynl, the M.D. seem's to be the perfect choice for this from 
what I've read, small size,easy hook up,good sound's and plenty of 
real time control. can you make up pattern's live from scratch or do 
you need to have every thing pre made then just play them when ready.
also is there any thing else I should know about M.D. befor getting 
it or maybe other gear I should consider. well thank's in advance for 
any info..
