audio midi setup app screen capture shown below - showing both active and 'offline' devices.
if in doubt delete everything, and start from scratch with an empty setup.
Ok this couse me a lot of problem , actually the PixMad say device offline because the device s driver was corrupted . At fisrt time i take a while to understand that because the device was showed in the midi set up .

Btw after restoring the driver , other apps did read the MTC but not PIXMAD .
