The 12 bell signals are simply routed to a ULN2003 or similar. I would have no problem soldering the appropriate voltage dividers to the µC lines to tap the signals.   phil99 said   Or if you can capture the audio from that video you could use Audacity to find the tone and timing of each bell. That's a great idea! Unfortunately, I have no idea how to do that with Audacity... @twofingers: The sequence of musical notes is important to me, or rather, when which µC output is switched at what point in time. Frank
