Re: Midi Clock and MOTU Midi Timepiece AV-USB

2012-05-03 by steve_the_composer

I believe you can send midi clocks in on several ports. The problem is routing multiple in ports to a single midi out ports without muting some of the midi clocks on the way out to a single port.

I thought that on the midi express, you can in effect route different midi clock sources to different midi outs.  Since the MTP AV seems to show up in clockworks, I would hope the same is possible.

I could be wrong. I will try to test this when I can--probably not tonight though.

If midi coming in to motu port 1 is being sent out to ports 2, 3 and 4 (including midi clock--no filtering) and midi coming in to motu port 8 is being sent out to ports 5, 6, and 7, I don't see how there could be any co-mingling of midi clocks.

Of course, logic doesn't always work; so I might be wrong.  (I will test when I can.)
