Interact with the BBFC by clicking on its buttons. Alternatively, you can use the following keys to press the buttons: 2 4 6 8 W R Y I ASDFGHJK You can change the bank by clicking on the corresponding part of the dial or by pressing the arrow keys. BBFC Sound Banks: Left - Built-in Songs 1-16 (OMNI Channel 1) Right - Built-in Songs 17-32 (OMNI Channel 2) Down - Notes F3-G5 Up - SFX This simulator starts in the "Notes F3-G5" mode, although it depicts the BBFC being in the SFX mode.
The BBFC is based on the Holtek HT3894A voice/melody IC, known for its use 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. Notes: - The star-shaped LED light currently does not reflect the current sound level, due to Scratch not having a dedicated block for retrieving it. Issues: - The simulator lights up which bank is selected - this is not how the original keyboard shows which bank is selected. The dial is manually rotated so that the appropriate bank is facing up. A separate sprite for the rotating dial could be added, but that would add complexity to the logic in the scripts. - Clicking the stop sign causes the pitch effect to reset. A recommendation is to always use the green flag to stop sound rather than the stop sign.
