Polyphonic ring tones
Early Ericsson mobile phones supported a proprie-
tary non-polyphonic format called eMelody. Owing
to the musical limitations of eMelody, and the pop-
ularity of creating, sending, and downloading ring
melodies, Ericsson and Sony Ericsson, together
with other manufacturers created the more
advanced non-polyphonic sound format – iMelody.
The development of mobile phones did not stop
with iMelodies, and today, many Sony Ericsson
phones (the Z200/Z208 for example), come with
built-in support for polyphonic sounds and ring
melodies, using the MIDI and SMAF formats.
Protocol
The Z200/Z208 has a hardware synthesizer chip,
built into the mobile phone. The software controls
the MIDI files, and makes sure they fit into the hard-
ware chip. It is possible to modify the dynamics of
the sound.
The Z200/Z208 supports the MIDI 1.0 detailed
specification. Please visit

MIDI – Musical Instrument Digital Interface – is a
specification for a communications protocol princi-
pally used to control electronic musical instru-
ments. MIDI is today a well known standard used
by musicians, composers, and arrangers.
A MIDI signal or file does not contain any music. It
contains text information as binary data about
what, when, and how an instrument or melody is
played. When this data reaches a synthesizer, the
synthesizer translates it into music.
The development from the iMelody format to the
MIDI format is a revolution in the sound quality. The
MIDI files are small, and perfect for mobile devices,
which have limited storage capacity.
Also, the SMF0, SMF1 and SMAF formats are sup-
ported. SMAF, which is a multimedia data format
invented by the YAMAHA® CORPORATION,
stands for "Synthetic music Mobile Application
Format". The SMAF specification defines a format
for multimedia files which can be played back on
handheld portable devices. Please visit
