Clock from USB to USB?

[Jesse Johannesen]

It's most likely that the TR-6s isn't compatible with the USB host. I've seen that with some other Roland gear, (though not all). Not sure about the Moog, I would see if it works on the DIN as well, and if not then check the settings to see if it's set up to block those messages. If USB doesn't do you right but you can get them working on DIN ports, then that's probably the best option at this point.
