How do I synchronize the Aeros & the BeatBuddy?

I’m very new to the Singular Sound system. i have the whole set up… Aeros, BB, Maestro, 2 button controller. I’m still trying to figure out all out but i don’t have a lot of time to spend with it. I’m playing in 2 bands and doing a lot of behind the scenes stuff… like writing set lists and laying everyone’s parts for them (don’t ask).

How’s do I get the serious
Aeros and the BB to pull up the same drum tracks for a given peice? For instance… Higher Ground…O go to the Stevie Wonder, speed it up to Chili Pepper tempo and then record a bass track on the Aeros to the BB drum track. When i play it back, it only pulls up the last drum track i used… and if it was a different song, that’s what it is. It doesn’t pull up what i used.
