When I used 2 Aardvarks Q10's they had a cable between them to sync up and the software numbered the tracks sequentially. I would bet MOTU would be similar. They were very unstable at times till I got a newer driver, even then you had to do a net stop and start when they had problems . I used the Aardvarks to record a live band every Saturday night for 4 years and always missed a song or 3 ,but it was great when it worked . Took a lot of cpu % to record a bunch of tracks too . When I lost the job I was happy to see them go and got a 2 channel maudio to replace as I hardly ever used more channels than that at home .
