Vortex Sound Research

A link to my setup:

Using Hermod, any sequence I play through it sounds great on Pluck, Bell, MCO, Plaits, even the Werkstatt. It's all tuned exactly where you would expect it.

However, if I run that same sequence through MI Edges, it's just a series of clicks and pops. I've deduced this is from the Edges playing extremely low notes.

I can't figure out why though. I'm pretty certain the Edges is calibrated and tuned correctly, so what gives?

Thanks in advance.
