Title: Can Midi Yoke reroute a MIDI Clock signal?
Post by Strauzzie on Mar 25^th, 2005, 11:33am

Hi all -

I have a situation that I think could be solved with Midi Yoke. I have a Korg MicroKontrol that I want to use to output Midi clock to two different laptops running Ableton Live. I could use a hardware MIDI thru box to split the clock signal to two outputs, but I don't have one; what I do have is a Edirol UM2 2x2 USB midi interface and an idea involving midi yoke. Would it be possible to run the Midi Clock signal into one laptop (via USB), and essentially forward this out to both outputs of the Edirol UM2 card? That would be amazing. Let me know if this is possible.

thanks,

Mark Strauss

Yeah, you could probably do this using only MIDI-OX. MIDI-OX can connect all the hardware devices together: If you can connect both the UM2 outputs to a MIDI-OX instance, and attach the Korg input, you won't need MIDI Yoke at all.

Alternatively, you could use the MIDI Sync transport in MIDI-OX to generate the MIDI Sync.

Midi-OX did indeed work, but with one caveat;

After seeing that the forwarding was working, I patched one of the outs of the UM-2 back into one of the ins, so that the timing would be equal to the other laptop (which has to travel from the other out, the length of a midi cable, and into an interface.) This works, but I have to introduce a +75.0 ms delay on the laptop using the UM2 in order to be synchronized to the other laptop. Using a midi thru box, this delay is not needed. Any ideas what could be causing this?

Running a hardware loopback will cause some latency, but not that much (I would think). MIDI has to be sent thru Windows, converted into a stream on the output and then converted back into Window messages on the input side.
