Aeros BB Syncing

Hi,

I have my Aeros and BB set up to have BB as slave and Aeros as master, using 6 x 6 mode. Everything was going according to plan, and then, all of a sudden, I’m not sure why, the Aeros started doing strange things to the temp of the BB. In one song, it changed the temp from 135 to 116, and then it did that for every song that I uploaded to the Aeros. In other words, it was no longer following the tempo of the BB, but was creating Aeros tempos on its own. I also noticed some arrows at the bottom of the BB interface going both ways and blinking. Did I inadvertently make some kind of setup change in either the Aeros or BB? Can’t quite figure it out. Any help would be much appreciated. Thx!
