Four output channel patches and headphones (Sennheiser PC 363D)

Hi to all. I'm a fresh French newby on this forum, and rather newby on MaxMSP too (one year of moderate practice).

I have realized patches with four channel outputs (for spatial effects) among which synthesized sounds and real time transformation patches.

I'm not fully equipped in terms of sound card, 4 HP set and the like, except for occasions when my compositions or rehearsed and played. I thus wanted to experience a quadraphonic-like sound, for testing and "debugging" purpose.

I bought a Sennheiser PC 363D headphones with integrated microphone. It is said to be 4-channels and even 5.1 compatible, and although it is mainly aimed at video games players, I hoped I would find a way to use with MaxMSP.

I use Windows 7 and the Windows driver shipped with the headphones by Sennheiser.

The driver is well installed, I can hear a 4 channels-like effect when configuring the headphones via the Windows control panel, alas I found no way to make these four output channels appear in MaxMSP setting Windows. Trying "DSP Status " and "I/O mapping" just shows me the headphone brand and model, but only with two outputs.

I Wonder if there's some trick to have MaxMSP see 4 channels in this configuration, a driver to install, a hidden setting (other than going to the DSP status Windows), a magical message to send to MaxMSP, whatever).

Hope I've been clear and thourough enough, thanks in advance for your suggestions and experiences.

MaxMSP-ly yours
