(musicNotationString,channel=0)

Parse music notation string and add resulting frequencies to the audio channel play queue.

Parameters:

musicNotationString : The notation might start with BPM character sequence, for example, "BPM120"
This defines the Tempo of the music. The default Tempo is 120.
You can set the current Octave with the O character, followed by the octave number (0-9). For example "O3" sets the third octave as a default one for the notes that will follow. The default octave is 4.
Capital letters represent single Note: C, D, E, F, G, A, B.
R character represents Rest (pause). It is treated as a Note by the engine, so all duration modifications could be applied.
# (sharp) symbol before Note raises the Note by a semitone (half-step up), for example, sharp C could be written as "#C".
b (small B letter) before Note lowers the Note by a semitone (half-step down), for example, flat D could be written as "bD".
To modify the octave of the Note - add a single number just after the Note: "C5" equals C from the fifth octave. "C+" will shift the octave up and "C-" - down. This octave shift doesn't affect the notes that will follow.
You can control the duration of notes that will follow using the L modifier. With L0 being the longest (Semibreve) and L6 being shortest (Hemidemisemiquaver).
The multiply character "*" after the Note will increase its duration by the factor of two. Two characters will increase Note duration by the factor of four.
The slash character "/" after the Note will decrease its duration by half. Two slashes will decrease Note duration by the factor of four.
The dot "." character after the Note increases duration by half. Two dots ".." will increase the duration by 1/2+1/4 and so on.
Underscore "_" character specifies that the current note is beamed with the following one.
