Settings Remark
RTTTL code Instead of selecting a melody from the list, you can create your own melody by using the Ring Tones Text Transfer Language (RTTTL) text format.
RTTTL is used to create ringtones which can be uploaded onto mobile phones but uses this format to create MIDI files.

An RTTTL code looks like:


The RTTTL code is divided into three sections that are separated by colons ":".
<name section>:<default value section>:<data section>
  • The <name section> contains the Melody title.
    For example: JingleBell
  • The <default value section> contains the duration (d), octave (o) and tempo (b) values.
    For example: d=8,o=5,b=112
  • The <data section> contains the actual melody.
    For example: 32p,a,a,4a,...,a,4g,4c6
There are two methods to enter the RTTTL code:
  • Method 1:
    Enter the RTTTL code in its original form in the "Enter RTTTL code" inputbox:
    <name section>:<default value section>:<data section>

    For example:

    Enter RTTTL code, method 1

    Do not use the Duration pulldown, Octave pulldown, Tempo pulldown and Melody title input field. These values will be changed automatically later.

  • Method 2:
    Only enter the <data section> values in the "Enter RTTTL code" inputbox and change the Duration, Octave and Tempo pulldown menus and enter a title in the Melody title input field.

    For example:

    Enter RTTTL code, method 2

Detailed information about the RTTTL name section, default value section and data section can be found here below:
  • The name section (JingleBell)
    A string containing the melody title.
    Maximum 100 printable ISO-8859-1 characters are allowed.

    For example: JingleBell

  • The default value section (d=8,o=5,b=112)
    Three key-value pairs separated by commas, which describes the melody defaults.
    If any of these three values is missing from the default value section, the following defaults are assumed: d=4,o=4,b=112.

    • d - Duration (Allowed values: 1, 2, 4, 8, 16, 32, 64, 128)

      For example: d=8

      Duration is how long a note is played compared to a whole note.

      • 1 - whole note (1)
        Whole note
      • 2 - half note (1/2)
        Half note
      • 4 - quarter note (1/4)
        Quarter note
      • 8 - eighth note (1/8)
        Eighth note
      • 16 - sixteenth note (1/16)
        Sixteenth note
      • 32 - thirty-second note (1/32)
        Thirty-second note
      • 64 - sixty-fourth note (1/64)
        Sixty-fourth note
      • 128 - hundred-twenty eighth note (1/128)
        Hundred-twenty eighth note
    • o - Octave (Allowed values: 0, 1, 2, 3, 4, 5, 6, 7, 8)

      For example: o=5

      This tool uses 9 octaves (octave 0 - octave 8).

      Octave 0 and 8 are not displayed in the image below but are used by this tool.

      Piano small octaves

    • b - Beats per minute (Allowed values: 25, 28, 31, 35, 40, 45, 50, 56, 63, 70, 80, 90, 100, 112, 125, 140, 160, 180, 200, 225, 250, 285, 320, 355, 400, 450, 500, 565, 635, 715, 800, 900)

      For example: b=112

      If a melody is assigned a "112 beats per minute" value, this means that the melody will get one beat each (60/112 = ) 1.867 second. If you want the melody to go twice as fast, you increase the beat to 224.

  • The data section (32p,a,a,4a,...,a,4g,4c6)
    The data section holds tha actual melody and is a set of string pairs separated by commas, where each string pair contains:
    a duration-pitch-octave and optional dotting (which increases the duration of the note by one half).

    For example:

    • Duration (Allowed values are: 1, 2, 4, 8, 16, 32, 64, 128)
      See also explanation above.

      Instead of playing notes you can also not play anything for a specific duration, the so called pause (p). How long a pause should last is indicated by:

      • 1 - whole rest (1)
        Whole rest
      • 2 - half rest (1/2)
        Half rest
      • 4 - quarter rest (1/4)
        Quarter rest
      • 8 - eighth rest (1/8)
        Eighth rest
      • 16 - sixteenth rest (1/16)
        Sixteenth rest
      • 32 - thirty-second rest (1/32)
        Thirty-second rest
      • 64 - sixty-fourth rest(1/64)
        Sixty-fourth rest
      • 128 - hundred-twenty eighth rest (1/128)
        Hundred-twenty eighth rest

      For example:
      The default value section: d=4,o=5,b=112
      RTTTL code: d6,8c#6.,16b,a.,8g

      The RTTTL code looks like: 4d6,8c#6.,16b,4a.,8g

    • Pitch (Allowed values are: a, a#, b, h, c, c#, d, d#, e, f, f#, g, g#, p)
      The pitch indicates how high or low a note should be played.
      If the pitch of a note is higher than another, it will be written higher up on the staff.
      If the pitch of a note is lower than another, it will be written lower down on the staff.

      The following pitch values (lower or upper case) are allowed:

      Pitch Represents note
      a A
      a# A# or Bb
      b or h B or Cb

      In most countries the C major scale is written as: C,D,E,F,G,A,B,C. In Northern European countries (such as Estonia and Denmark) the C major scale is written as: C,D,E,F,G,A,H,C.
      c C
      c# C# or Db
      d D
      d# D# or Eb
      e E or Fb
      f F or E#
      f# F# or Gb
      g G
      g# G# or Ab
      p Rest or pause (no sound)

    • Octave (Allowed values are: 0, 1, 2, 3, 4, 5, 6, 7, 8)
      See explanation above.

      For example:
      The default value section: d=4,o=5,b=112
      RTTTL code: d6,8c#6.,16b,a.,8g

      The RTTTL code looks like: d6,8c#6.,16b5,a5.,8g5

      RTTTL codes for mobile ringtones only uses 4 four octaves (4,5,6,7).
      Octave 4 - Note A is 440Hz
      Octave 5 - Note A is 880Hz
      Octave 6 - Note A is 1760 Hz
      Octave 7 - Note A is 3520 kHz however uses 9 octaves to create MIDI files.

    • Optional dotting (Allowed value: .)
      A dotted character (.) can be specified AFTER the duration-pitch-octave pair.
      A dotted duration is one in which a note is given the duration of "itself + half of itself."

      For example:
      A dotted quarter note C, octave 6 (4c6.) has a value of a quarter note plus an eighth note.

      A dotted eighth note F#, octave 5 (8f#5.), has a duration value of an eighth note plus a sixteenth note.

    Herebelow are several examples (default value section: d=4,o=6,b=63):
    • If no duration or octave specifier are present, the default applies.
    • The character p indicates a rest (pause). Because rests don't occur in an octave, you don't use an octave indicator.

    [duration]-pitch-[octave][dotting] pair Explanation
    8f#5 1/8 note F#, octave 5
    8d5 1/8 note D, octave 5
    8p 1/8 pause
    4p 1/4 pause
    4p. 1/4 + 1/8 pause
    p 1/4 pause
    c5 1/4 note C, octave 5
    8d 1/8 note D, octave 6
    2e. 1/2 + 1/4 note E, octave 6
    4c5. 1/4 + 1/8 note C, octave 5
    8d#6. 1/8 + 1/16 note D#, octave 6
    c# 1/4 note C#, octave 6
    d 1/4 note D, octave 6
