Sup everyone...

I am buying a second vci 100 ( I rather stay away from the new ones but that's a story for a different day... ) and I was wondering if anyone has ever successfully connected 2 vci's to one mac running the latest traktor? I heard I could use apps like midipipe to channel the second vci to channel 2 in traktor but will this work and how will midipipe differentiate messages being sent from both controllers simultaneously?

Any help would be greatly appreciated. I have a huge gig in Belgium in a few weeks and I need to sort this out asap... so thanks in advance for ANY help...!
