My point was simply that you shouldn't put all your work into the project and then realize too late that the concept has flaws. I'm learning a lot about music and MIDI from your project. For example: First, I saved the sheet music for "Hark! - The Herald Angels Sings" as a CSV file (s. screenshot) from a MIDI file for comparison (D4, G4, G4, F#4, G4,...). In addition, the formulas (or functions) for Transpose SPN, Convert SPN -> Frequency, SPN -> MIDI(Number). By the way, before you posted your project, I was also working on ding/dong doorbells – as a PicoMite project. The reason was a faulty CR2032 battery in my wireless doorbell. I discovered that CR2032 batteries are perfectly suited for real-time clock (RTC) chips, but are often a frustrating source of errors in many other applications. But I digress ... Have a good evening ... Michael
