8 notes, 3 pins, 2 buttons. What do?

MicroScale.js

/*
JavaScript code to play a C major scale on the microbit. Pin0 is reserved for the sound output device.
So really we have 2 pins and 2 buttons
P1 = C3, P2 = D3, A = E3, B = F3, A+P1=G3 A+P2 =A3 , B+P1 =B3 , B+P2=C4 (values in code are actually hz)
