It’s now called the Behringer Dual-Phase, and it is completed and being shipped from the factory, so will be available soon for pre-order from the retailers that carry Behringer products. $159 USD.

There’s a nine plus minute video, way to talky for my taste, but hopefully more videos soon.
That it is shipping now is good to see.
A guitar thing in a lot of ways, but with the CV inputs, likely usable in other ways too.
ADDED : Andertons pre-order.
