Reply to 2 midifighters....fighting

im running traktor 2 pro with one midi fighter and deckalize mapping and everything was working shweeet.

toevening my mate came over and we hooked up a second midi fighter...selected the appropriate ins and outs for each one....they both work and do what they are supposed to, however at certain times one midi controller will activate effects, loops and beat juggling on both decks simultaneously! it seemed to be random and got pretty frustrating.

is anyone able to help? i thought it may be a midi channel issue so i changed the channel on one and that stopped it from working entirely. when i changed it back to the original channel it worked but with the same issue.

we are djing a party on the weekend and would love to have it sorted by then.

cheers guys.
