I want to give this interface a full five stars as it's a great device and does its job pretty well.
However, I find they're wrongly marketing it as a DC-coupled interface, even with the disclaimer it's only 4vpp, as it's pretty useless for CV control purposes. In some cases it can't even trigger gates.
I'm guessing this is the reason B-Stock units are such a common sight.
Other than that, excellent little audio interface.
