Latency with drone

[Steve]

Ok, this is an interesting issue. Let's see if we can do some tests to see where in the chain the problem lies. Lets try to get the simplest signal chain into the NDLR MIDI A possible:
one external clock source => midi cable=>NDLR MIDI A and see it's still messing up
if yes, then replace the midi cable.
if still yes, try one more external clock source.
if no the problem went away, start putting things back in the chain until we see what is causing the hubbub.

One thing I noticed you mention is that the MioXM isn't recognizing the NDLR via USB host, and I was thinking it may not be providing quite enough power. You may be able to get the host to recognize NDLR by using a powered USB Hub, and though I've had mixed results with those in the past, it may be worth a try.

I'll get Steve and Darryl to take a look at this and see if they've got any suggestions as well.
