The Aeros and the BeatBuddy both can control one another depending on which is the MIDI Transmitter (master).
The Aeros as the transmitter is more capable of choosing a specific BeatBuddy Part handsfree however, since you can transition at any time and it will tell the BeatBuddy to transition at the last measure of the Aeros part into the same part # out of 6 as the Aeros, it also can be set (as of version 5.1.0) to tell the BeatBuddy to play the outro command when the song is stopped on the Aeros.
The BeatBuddy’s method of controlling the Aeros is more limited.
