Stereo Quadraphonic 3D

In each case (Cubase and Sound Forge Pro) I create four different stereo systems and assign them the following positions in three dimensions - Sound card #1 (Quad system #1)      Front bottom      Front top Sound card #2 (Quad system #2)      Rear bottom      Rear top which defines all three dimensions - left, right, front, rear, up and down - as shown in the captures below. Cubase Outputs Sound Forge Pro Outputs The images above also show that in addition to those four stereo systems (two quadraphonic systems), I assign the mono subwoofer output of each sound card to separate sides of an additional stereo system which creates a fifth stereo system exclusively for bass subwoofer output. Since bass is omni-directional, which means the bass will be present no matter where the subwoofers are placed, placement of the subwoofers is not an issue.
