I want to use Giga and Cubase to produce music (mix cubase and giga outputs). Whats the best way to do this? The ways I can think of are:

1. Take the analog output from Cubase and Giga and mix them in a external mixer (in this case whats the best way to have multiple analog output from Giga, use many sound card or some sound card where multiple outputs are available or how else?).
2. Capture the output from Giga into a wave file and bring that into cubase (in this case For example, lets say you have eight giga tracks, can you record each track into a seperate .wav file at one time (or do you have to record track by track eight times). Also when you bring the .wav file into cubase then will have problem syncing them with the midi tracks. Is there a better way to do all this?

Is there any other way to mix giga and cubase outputs so that I can produce music?
