In computer programming, a C string is a null terminated sequence of characters.
I have tried all sorts of things with the notes themselves, morse code including leaving out all but the 'C' notes, I've even looked at it as paper tape code and punched card code. I wonder if DreamLoverLabs don't actually know which notes are which on the stave, particularly the bass stave where the two dots show which note is 'F'. Middle 'C' is one line above the bass stave and one line below the treble stave. There is of course another 'C' on each of the staves. I've looked at one stave at a time, and all three at once, as the G/A note being a boolean to select whether or not to use the treble stave note.
I think this has just been miscoded and I'm not going to waste any more time on it. Apparently we only have to wait for the sample production run to complete and they will announce anyway.
