Sure, the stereo analog output on the card receives the last pair in the HDSP Mixer (ch. 63 & 64 when operating at 44.1/48k). If you route all your playback to these channels you'll get a submix at the analog out. Of course, this would reduce the channels available for routing to the other computer by 2.

Jose,

With totalmix you can route anything to anywhere! So you can set up a mix on outputs 63 and 64 using all of the other 62 channels. You can also set it up to send each channel (eg. 1 through 62) to anywhere you want them to go!

I found it helped to think about totalmix like a 64 x 64 matrix (press x for the matrix view). You have 64 freely assignable outputs.

So bottom line yes you can do what you want to do!

Hope this helps,
Isaac.

yea, keep all of your 1:1 routings, but add some routings by using the submix view and selecting output bus 63/64.  Once that output is highlighted (or rather not dimmed) you can make a mix of all of your inputs and playback channels which plays out madi 63/64 and the analog output.  Since the analog output is unbalanced it might be wiser to go to your other computers madi card and route input 63/64 to your monitor outputs.  This way you would not have to switch anything.  When you are composing you hear your temp mix through madi out 63/64 of the arrange computer -> madi in 63/64 of the layback computer -> analog output from layback computer to studio monitors.  Then when you record you can listen to either depending on what you have selected in totalmix.
