Elektron Musical Instruments

can i ask what your sync settings are in Cubase and the MD?  what's 
your latency setting in the audio card?  what midi interface are you 
using?  trying to see why we seem to get different results.

also, possibly most important, what TRIG mode (under midi map editor) 
are you using in the MD?  i could actually hear noticeably bad sync 
using STRT mode and have found QUE mode is the most solid, for me 
anyway...
