Can't use two outputs at the same time?

[alsonax]

I'm trying to connect my SL 88 Studio to 2 USB based synthesizers (standalone Pianoteq box and PC). I've tried two different setups:

1. Using the built-in USB ouput + 1 MIDI to USB cable. In this case connecting the built-in USB seems to block any output on MIDI OUt 1. As soon as I disconnect the USB cable, MIDI OUT 1 works fine.

2. Using 2 MIDI to USB cables. As SL 88 has 2 MIDI outputs, I figured I would try using these instead of the built in connection, but I have the same problem, where MIDI Out 2 seems to take precedence over Out 1 - as long as Out 2 is connected, nothing is coming from Out 1. If I disconnect Out 2, Out 1 works fine.

What am I doing wrong? What is the point of having multiple MIDI outputs if they can't be used at the same time?

Not sure, sounds like an SL88 issue. try one of these; send one Midi out from the SL88 into this box which then should redistribute the signal to two midi outs:

MIDI Solutions Merger; Two Input MIDI Merger

I was trying to avoid buying another box, but I guess there's no better solution.

Thanks

...I had the same problem even when using a Thru box (MIDI in powered). One of the MIDI2USB converters is a cheap one and it was probably pulling more current than what it should, preventing the other one from working, even though it was fine alone. I switched this converter for a new (and probably better) one, and now I can use both MIDI outputs directly on the SL88 without a separate Thru box.
