Hi! i just recently purchased cubase VST 5.0 and i love it except for 
one thing, i cant get my midi to work properly! i hope someone on 
here can pleeeeeease help me out.what happens is this: the first 
measure gets cut off (no audio or midi signal) then after it loops 
through once, the last half of the 4th measure gets cut off abruptly 
while the first measure plays?? This happens for every one of my 
synths and midi connected instruments but doesnt happen if i instead 
use a vst instrument on the track?? I leave a full measure beforehand 
for my program change messages and everything to get sent to my 
An1X's as i know they need about half a second to kick in. in fct i'm 
not even sending any program change messages but do that as a 
precaution. i leave more than enough time for that..can someone 
please help? i've got no hair left from ripping it all out trying to 
figure this out!
