This post details how to replicate my quadcopter ESC startup music. Note that a BLHeli32 ESC or one with compatible music functionality is required.

Turn on music for all four ESCs, and set `Gen. Length` to 11, `Gen. Interval` to 0. In the `All ESC together` section, make sure the checkboxes for `Show 1/X for length`, `Show Space` and `Play 1 Octave lower` are all set to enable.

Then, set the music data as follows.
