Yesterday's big release adds an "…on Song Selection" option after Settings > Tempo & Pitch > Send Tempo to BeatBuddy. With both of these options turned on, BandHelper will set the tempo on a connected BeatBuddy when you select a song, without starting the BeatBuddy playback. With this new setting turned off, BandHelper sets the BeatBuddy tempo and starts playback when you start the tempo function, as before.
