How are backing tracks meant to be used?

I have the bass line for a song saved in the backingtracks folder on the SD card. This backing track has been quantized to 78 BPM and aligned to start right on beat. I have a 78 BPM beat in BeatBuddy that I want to use with this backing track. My BB is master. Aeros is slave.

Let’s say I have several backing tracks on the SD card. How do I make the correct backing track start when the BB sends the MIDI Start command to the Aeros?

How do I make the backing track audible? What routing is required?

Or, do I have a fundamental misunderstanding of what Aeros backing tracks are and what they are intended to do? If so, please point me to some good tutorials and usage examples.

A backing track works the same way as a recording on the Aeros, and it is routed in the same manner. To import your backing tracks, you can follow this video guide:
