Hello,

the attached Patch workarrounds the fact that the device appears to be working ASYNC, however it will be hanging, not playing or capturing a single byte.

The 2 channel Altset kind of works, but sounds garbage. The 18 channel Altset works as intended. It needs to be cutted down to be usefull, channels 16 and 17 are the default "PC" outputs, i attached a asoundrc for the device, providing 9 stereo interfaces. In the default configuration with no other devices attached, mxout4 to mxout9 will be working stereoi outputs bound to faders on the mixer. I have not yet tested the MIDI interface.



Kind regards,
Julian
