The SD2 connects to the PC via midi. I assume it comes with either a Midi or USB Cable to connect with? How about a midi driver as well? I don't have the SD2 here, sorry.

Once you have it connected correctly and the driver installed, open Biab and go to Opt/Pref/Midi Driver. Select SD2 in the midi out and also set your "soundcard" (same menu in Biab)to one of the Edirol SD selection.

Connect your headphones to the headphone jack and see if you can NOW hear playback thru the SD2 while Biab plays a song with midi instruments. If you can hear playback the SD2 is connected and the driver is working correctly.

I assume the Mackie connects to the PC? I am not familiar with Firewire connections. You may not need the Firewire if you are simply using the mixer for playback only.

You would run the line out of the SD2 into either channel 3 & 4 or probably the "tape in" input on the mixer. The tape in might require you to use a "control room" button on the mixer as well to "send" it to the main outs/headphone jack etc . . .

You may need to have to buy a cable for the SD2 to 3 & 4 set up, otherwise try the tape in routing.

One last thing: To select a "higher bank" midi patch in Biab, click the (+) button to the right of "gm2". Then go to "open patch" button and click that. Make sure BB is selected at top of next menu and scroll to SD2 patch (located near the bottom) and select it. It will automagically generate your SD2 higher bank patches. Then click the "update" button before closing that menu and you will be set.
