1)....up-date 6.20 is to old for the vci 1.2
you need to up-date to the new 7.1
2)....when you trun the vci-100 on you will see a little red light with the lable data send come on
now wait another 20 second and some of the other buttons ( cue,play and other ) will light up now you are ready to go and do the MIDI set-up in mixvibes
if the other button don't light up ...try another USB port
3)...for more info on how to set-up the MIDI in mixvibes and how to set-up the sound card for the vci
have a look at this post
