I don't know where the numbering system came from. It was in Kai's original code and he also had some pieces of classical music that he used during testing, so I think it must be based on some source code that he found.

As far as I can tell... The note C is 30, hence C# is 31, D is 32 etc
I tested this with a guitar tuner pressed to the radio and it seems to be reasonably accurate.

Timing of notes is again a mystery, from Kai's original code. I think 1 = approximate 27mS

Thanks for the reply Roger, I was curious to understand how the melodies were composed.
