The BBFC is based on the Holtek HT3894A voice/melody IC which is famously used in the Nichols Electronics OMNI ice cream truck music box. This chip appears to have been packaged into a COB-on-daughterboard form for use in the keyboard. The audio used in this simulator is provided by @whc2001 on YouTube. Issues: - The star-shaped LED light currently does not reflect the sound volume level due to the limitations of the Scratch audio system. - The simulator lights up which bank is selected - this is not how the original keyboard works. The dial is manually rotated so that the appropriate bank is facing up. See impostorboo's remix for an implementation of it.
