Can I use my Flux with DDR Ultramix on the Xbox?
Yep. Again, you’ll need a converter. The Gemini Game Elements converter works well with the Flux and is available at chains like Wal-Mart for $13. However, and this is important, there is no way to disable the corner panels of your Flux within the Ultramix 1 game options (unlike the PS2 DDR controller on/off option) – this could lead to perceived missteps during play. The corner buttons on a native Xbox compatible dance pad are disabled automatically when Ultramix detects that a pad is present, but using the converter makes your pad look like a standard Xbox controller. The only way this issue can be avoided is to make your own control box using the circuit board from an Xbox soft pad or by adding a cable to a soft pad controller for passthrough to your Flux. Ultramix 2, however, does have the option to disable the corners, so UM2 players will do just fine with a standard converter.
