I am running Onyx 4.5.1200.0
when i plug in the playback module i was prompted to update the firmware.
firmware updated from 2.26 to 3.4
under Menu > syatem > DMX settings
device shows as Martin USBDMX V2 (On Wing2) originaly name was 0, i changed this to 2
Obviously it would be desirable to have this as a separate playback module currently the lables and mechanical faders just clone any action on the main console
