No apology necessary. I did quote your unsupported statement in my first post. All I can tell you is I hauled the old units out of the garage, installed the driver, did all the voodoo involved, got input but no output to any of the 16 channels. Using the Test Mode of AudioMIDI output to the various external units did work…but not through Cubase.
So…back to the garage and back to the MOTU units I bought to replace those things. I thought it’d be worth a look…because the MIDI timing was always superior to the MOTU’s.
If you get a chance…try two units and see what happens. Also: how many inputs and outputs did you hook up? All 8? Did all 8 outputs run simultaneously and properly to external units?
