So, to explain, in version 5.0.0 the Aeros can now send MIDI commands any time you open a song, this can be set in the song’s settings
So you can send any combination of a sequence of MSB + LSB + PC commands that can open a BeatBuddy song as you open the Aeros song.
We will not exactly do what you asked, but something very close that can achieve the same task! So I will tag this as #implemented
