I just purchased a MidiSport 2x2 interface. I come OUT of the MidiSport into a Midiman 1x4 Thru Box then into my sound modules. The Thru box has a small green LED that lights to signify it's receiving midi. It does not light up. I have checked all my cables and everything is fine. I assume since the Midisport is powered via USB that it is not getting enough power to operate the thru box.
I have used two other interfaces and had no problem(Tascam 428 and Evoulution UC 33) The 428 was also powered by a power supply, Although the UC 33 was powered via USB I noticed it required 250mA. The Midisport requires 0mA...Is this why the Thru box is not operating? Is there a workaround for this?

The 2x2 works fine. I thought of powering the Thru box but someone on anohter site had a bad problem. This is what they said about the Midiman 1x4 Thru box:
"
that's the same one i had. it caused many problems and made my midi set-up totally unreliable. then one day i tried plugging in the optional 9v power supply to see if that would make things any better, and it blew all the fuses on my sherman qmf... it was then sent directly out the window :) "
I emailed Midiman, they said a may need a "Midifix" file to apply to my PC. I believe the 2x2 and the Thru work fine. Since I tested them separtely. But together they won't.
Thanks for the info :)

I'm not an electronics whiz but I guess that some sort of active circuit is required to maintain the signal integrity.
I have an old Yamaha YME8 merge box...basically a brick shithouse of a unit and it required a pretty beefy power supply.
Its not the fact that its a merge box, I think its the fact that it has to drive several other lines.
:) Munkee, make sure the 2x2 is working by connecting directly
:) Munkee, make sure the 2x2 is working by connecting directly to a module. The 1x4 thru box may require extra power according to the m-audio website.
Note the bold print. Hope this helps,
