On my previous article told that I would add the codes of my "3 Octave Music Player Project". The codes can be downloaded from here, but you need a password to download the file. 

The code is licensed under GNU, so you need to obey GNU license and include my name if you would like to use it in any of your work.

*Quick Start Guide:

a) Files required:

musicplay.m - Main function file
returnNotes.m - Note letter to note number equivalent conversion function

b) Usage

0) Change MATLAB active directory to this directory.

1) Enter left and right hand notes in a char array using space between notes.

*Notes should be entered as follows: NoteLetter[Sharp(#)symbol]OctaveNumber.

Example: C#4 D5

* Since notes will be inside a char array, they should follow the rule below:
x=['NoteLetter1[Sharp(#)symbol]OctaveNumber1 NoteLetter2[Sharp(#)symbol]OctaveNumber2'];

*** Square brackets are optional, but single quotes are obligatory!

Example: i=['C#4 D5'];

* For neat coding, you may want to go to next line. To go to next line, close single quote
('), add three dots (...), go to next line, start line using single quote again and leave
a space before entering new note.

Example:

j=['C4 D3 G5 D4 D4 E4 A4' ...
' C4 C4 G5 F#4 E4 A4'
];

2) Call function to play the notes.

After writing notes for both left and right hand (see below (3) if you have no notes for left hand)
call function using: musicplay(rightHandNotes, leftHandNotes, defaultOctave, startFromLeft,
playFromLeft, waittime, sampleCount, samplingFreq)

At least two arguments (rightHandNotes, leftHandNotes) should be given so that others will get
their default values.

3) If you have no notes for leftHandNotes:

* You should create a silent note using x=['N0'] and playFromLeft argument should be zero.

*** This will bypass playing from left hand notes.

4) More questions on usage or looking for examples?

Execute: run('./twinkletwinklelittlestar_regular.m') - for Twinkle Twinkle Little Star
Execute: run('./someonelikeyou_regular.m') - for Adele - Someone Like You
Execute: run('./someonelikeyou_numbereq.m') - for Adele - Someone Like You (number equivalent of notes)
Execute: run('./titanium_regular.m') - for David Guetta - Titanium

Execute "doc musicplay" on MATLAB

c) Troubleshooting:

Here are some problems that you may experience and their solutions:

1) Subscript indices must either be real positive integers or logicals. - The first note at first line
starting after single quote must not have a space in front of it.
2) CAT arguments dimensions are not consistent. - You used multiple lines, but forgot to place "..." at
the end of the lines.
3) In an assignment A(I) = B, the number of elements in B and ... - There are no spaces between notes
or octave number is missing (e.g. you only wrote C instead of C4).
4) Index exceeds matrix dimensions. - You have more than one space between notes.
