Multiple simultaneous buss outputs in cubase VST/5

[MiXit-G]

I have a song in cubase of about 8 tracks, i want to condense these down into 4 subgroups (1 drums, 2 Keys, 3 samples, 4 guitar) so i can transfer them via adat light pipe to my fostex 1624 for overdubs.

I'm using scope fusion platform with the luna EX card and so far i can only assign the cubase master out buss to 1L1R one stereo or 2 mono, i need four!!!

I have selected the 24 asio source module in the routing window and incresed the channels to 4.

Effectivly i want to go- 4 channels from cubase to four channels lightpipe into the fozzie.

I could go 2 but i want more flexability with playback levels.

Can i do this???
