The Scheiber matrix is QS matrix like, but without 90 degree phase shifts, it should be easier to implement in software (or with a mixing board and some phase reversals) than QS.
I haven't worked thru the math of Scheiber encode/QS decode, but it seems like it would be almost indistinguishable from QS encode/decode.
As with QS, the Scheiber matrix could also be decoded with Dolby Pro-Logic decoder(s) and the simple DynaQuad speaker matrix.

A QS decode of the Scheiber encode should have only very minor (probably inaudible) differences:
- The phases of the back channels are 90 deg different with QS than they are with Scheiber.
- The back channels are in phase with each other in QS. They are in opposite phase with Scheiber decode.
The only difference between the Scheiber decode and the EV-4 decode is the parameter values.

The above can decode Scheiber, QS, EV-4, Dynaquad, and Dolby Surround.
Here are some other ideas:
