I have a feeling it may be a 2011 era build of the emulator and further downloads of MAMEUI just inheriting its options if it is the emulator and not the rom itself. My cousins had an even earlier build of the emulator from roughly late 2008 and it played Logic Pro 2 with the same bugged audio. That said I still would like to examine a download of Logic Pro 2 from the late 2000's or very early 2010's just incase.
Considering it's one of those accounts that just posts brief gameplay footage for an external site I'm not going to get an answer- the game is relatively unknown and there's hardly any footage of it anywhere. I shared the video clip mostly as a point of comparing the unbugged and bugged audio of the first stage.
