Reply to Traktor crackling when loading a track WHILE sending midi clock & using JackRouter

Just got a VCI-400 and am having a serious issue!
When sending midi clock Traktor crackles/ freezes whenever I load a track while another is playing.
When I turn off the Clock Send... no issues.

I am sending clock to Live via MidiYoke and piping audio to Live via JackRouter.
Changing buffer size in Jack, clock offset in Traktor, and having EXT enabled in Live have no effect.

It never did this on my former soundcards (MBox Pro3, NI AK-1, M-Audio FW1814), then again, the clock signal was always so squirrelly in Live I gave up on it and have been using ClyphX commands to +/- BPM in Live manually...

For some reason, though, once I got my VCI set up and tried syncing...it works! Still jumps around a little in Live but behaves well enough to use for DJ stuff.

This would be a miracle for me as I'm using Live as a sampler/FX unit and my sets go all over the place tempo-wise. I'm trying hard to simplify my DJ workflow, esp after replacing a crap ton of cheap controllers with the VCI...any help is most appreciated!
