Good day luminaries....

My old 8Port SE midi patch bay is giving me grief so I think I'm going to need a new midi patch bay.

I'm using a Roland JV-30 (keyboard controller), Roland MBD-1, Roland MVS-1, Proteus FX.
So, I need a 4in/4out.

I was looking at the Midiman Midisport 4x4 and have read many less than favorable reviews but those reviews were a couple of years old.
I'm somewhat ignorant of the USB interfaces or any issues that may exist.

I don't know of any other manufacturers.

If anyone could offer some direction I'll thank you in advance.

I'll probably post on the Sonar form too should any of those responses be helpful to this inquiry.

Carry on....
