<h1>Music Macro Language evaluator<a class="headerlink" href="#music-macro-language-evaluator" title="Permalink to this heading">¶</a></h1>
<p>The MML object implements acustom MML evaluator to allow simple and efficient
music composition within pyo. The language’s rules are explained below.</p>
<p>The MML object generates triggers on new notes with additional streams to
handle frequency, amplitude, duration and custom parameters. See the object
documentation for more details.</p>

<li><p>A comment starts with a semicolon ( <strong>;</strong> ) and ends at the end of the line. This

<li><p>A musical voice is represented by a single line of code.</p></li>
<li><p>We can break a long line into multiple short lines with the backslash ( <strong>\</strong> ).</p></li>
<li><p>The symbol equal ( <strong>=</strong> ), preceded by a variable name in UPPER CASE, creates a
macro. The remaining part of the line is the macro body. Anywhere the
pre-processor finds the variable name in the music, it will be replaced by the
macro’s body.</p></li>

<h2>Realtime Processing of the music<a class="headerlink" href="#realtime-processing-of-the-music" title="Permalink to this heading">¶</a></h2>
<p><strong>Voice number</strong></p>
<ul class="simple">
<li><p>The symbol #, followed by a number indicates the voice number for the line. This should be
the first token of a line. If missing, the line defaults to voice number 0.</p></li>
</ul>
<p><strong>Notes</strong></p>
<ul class="simple">
<li><p>The letters <strong>a</strong> to <strong>g</strong> correspond to the musical pitches and cause the
corresponding note to be played.</p></li>
<li><p>Sharp notes are produced by appending a <strong>+</strong> to the pitch value, and flat notes
by appending a <strong>-</strong> to the pitch value.</p></li>
<li><p>The length of a note is specified by an integer following the note name. If a
note doesn’t have a duration, the last specified duration is used. Default
duration is the Sixteenth note. Length values are:</p>
<ul>
<li><p>0 = Thirty-second note</p></li>
<li><p>1 = Sixteenth note</p></li>
<li><p>2 = Dotted sixteenth note</p></li>
<li><p>3 = Eighth note</p></li>
<li><p>4 = Dotted eighth note</p></li>
<li><p>5 = Quarter note</p></li>
<li><p>6 = Dotted quarter note</p></li>
<li><p>7 = Half note</p></li>
<li><p>8 = Dotted half note</p></li>
<li><p>9 = Whole note</p></li>
</ul>
</li>
<li><p>The letter <strong>r</strong> corresponds to a rest. The length of the rest is specified in
the same manner as the length of a note.</p></li>
<li><p>The letter <strong>o</strong>, followed by a number, selects the octave the instrument will play in.
If the letter <strong>o</strong> is followed by the symbol <strong>+</strong>, the octave steps up by one. If followed
by the symbol <strong>-</strong>, the octave steps down by one. If a number follows the symbol <strong>+</strong> or <strong>-</strong>,
the octave steps up or down by the given amount of octaves.</p></li>
</ul>
<p><strong>Tuplets</strong></p>
<ul class="simple">
<li><p>Notes surrounded by brakets ( <strong>(</strong> and <strong>)</strong> ) act as tuplet. Tuplet length is specified
just after the closing bracket using the same values as for a note duration. Length of
each note in tuplet will evenly be <note length of tuplet> / <count of notes in tuplet>.
If not specified, tuplet duration defaults to 5 (quarter note).</p></li>
</ul>
<p><strong>Tempo</strong></p>
<ul class="simple">
<li><p>The letter <strong>t</strong>, followed by a number, sets the tempo in beats-per-minute.
If the letter <strong>t</strong> is followed by the symbol <strong>+</strong>, the tempo increases by one. If followed
by the symbol <strong>-</strong>, the tempo decreases by one. If a number follows the symbol <strong>+</strong> or <strong>-</strong>,
the tempo increases or decreases by the given amount of BPM.</p></li>
</ul>
<p><strong>Volume</strong></p>
<ul class="simple">
<li><p>The letter <strong>v</strong>, followed by a number between 0 and 100, sets the volume for the following
notes. If the letter <strong>v</strong> is followed by the symbol <strong>+</strong>, the volume increases by one. If
followed by the symbol <strong>-</strong>, the volume decreases by one. If a number follows the symbol
<strong>+</strong> or <strong>-</strong>, the volume increases or decreases by the given amount.</p></li>
</ul>
<p><strong>User variables</strong></p>
<ul class="simple">
<li><p>The letters <strong>x</strong>, <strong>y</strong> an <strong>z</strong>, followed by a real number, are user-defined parameters. They
can be used to control specific parameters of the synthesizer.
If the letter is followed by the symbol <strong>+</strong>, the value increases by 0.01. If followed
by the symbol <strong>-</strong>, the value decreases by 0.01. If a number follows the symbol <strong>+</strong> or <strong>-</strong>,
the value increases or decreases by the given amount.</p></li>
</ul>
<p><strong>Random selection</strong></p>
<ul class="simple">
<li><p>Random choice within a set of values can be done with the <strong>?</strong> symbol, followed by the
possible values inside square brackets.
Ex. ?[c e g b-] ; the note is a random choice between c e g and b-.</p></li>
<li><p>Random choice between a range can be done with the <strong>?</strong> symbol, followed by the range inside
curly brackets. If two values are presents, they are the minimum and maximum of the range.
If there is only one value, the range is 0 to this value and if the brackets are empty, the
range is 0 to 1.
Ex. v?{40 70} ; volume is set randomly between 40 and 70.</p></li>
</ul>
<p><strong>Looping segments</strong></p>
<ul class="simple">
<li><p>The symbol <strong>|:</strong> starts a looped segment and the symbol <strong>:|</strong> ends it. A number right after the
last symbol indicates how many loops to perform. If missing, the number of loops is two (the
first pass + one repetition). It is possible to use loops inside other loops. There is no
limit to the number of levels of loop embedding.</p></li>

<p>MML outputs many signals identified with a string between brackets:</p>
<div class="line-block">
<div class="line">obj[‘freq’] returns an audio stream of the current note frequency.</div>
<div class="line">obj[‘amp’] returns an audio stream of the current note amplitude.</div>
<div class="line">obj[‘dur’] returns an audio stream of the current note duration in seconds.</div>
<div class="line">obj[‘end’] returns an audio stream with a trigger at the end of the sequence.</div>
<div class="line">obj[‘x’] returns an audio stream with the current value of the <cite>x</cite> parameter.</div>
