Hi guys,

Thanks for your replies.

JCR, I tried connecting the Quadra Thru in the manner you suggested, but still to no avail. Perhaps the Quadra Thru is wired differently than the Merger?

In any case, I will likely be returning the Quadra Thru and replacing it with a Molten Voltage MIDI Splitty, which should hopefully do the trick.

Thanks again for your help.

Best,

Andrew
