Voice Sequence

[edit] Description

Voice Sequence files are used to store musical and note data for the VOCALOID2 engine. The format is based on a combination of the MIDI and INI formats.

[edit] Information

While not yet fully documented, some information is known about a number of sections of the Voice Sequence format.

[edit] Common

Contains information about the application and synthesis engine, with known properties being:

• Version - the version number of the synthesis engine used to create the file
• Name - the name of the track
• Color - the background colour of the track button
• DynamicsMode
• PlayMode

[edit] Master

This section is currently only known to contain one property, whose function is not currently understood

• PreMeasure

[edit] Mixer

This section contains information about the attributes of the synthesizer mixer. Known properties are:

• MasterFeder
• MasterPanpot - dictates how much panning (the balance between left and right stereo channels) should be applied to the master track
• MasterMute - it is assumed that this should mute the entire master track, although this is currently unverified
• OutputMode
• Tracks - the number of tracks contained in a given sequence
• Feder#
• Panpot# - as with MasterPanpot, dictates the panning to be applied to a given track. The # is the index (zero-based) of the track to which this property refers
• Mute# - as with MasterMute, it is assumed that this mutes a given track (unverified), with the # again specifying to which track this refers
• Solo# - sets solo mode on a given track. If this is set to 1, all other tracks (except those with this also set to 1) should be muted

[edit] EventList

This section contains the Vocaloid commands that are being sent. Its properties consist of a list of numbers corresponding to times at which events should be issued, each of which is assigned a value in the form ID#XXXX, where XXXX is the zero-based index of a given event group.

[edit] ID#XXXX

These sections contain information about Vocaloid commands, with the properties varying depending on the value of the Type property. Known types and properties are:

[edit] Singer

• IconHandle - a reference to a further section containing more information on the specified singer

[edit] Anote

• Length - the length of a note (the unit for this is currently unknown)
• Note# - the number of a given note (integer values and how they correspond to musical notes are currently unknown)
• Dynamics
• PMBendDepth - portamento bend depth, i.e. the amount by which to pitch-bend the current note
• PMBendLength - portamento bend length, i.e. the length of a pitch-bend for the current note
• PMbPortamentoUse
• DEMdecGainRate
• DEMaccent - apparently refers to the accent value of the Note Expression property, although none of these terms are explained anywhere else (presumably refers to [| musical accents] in some way)
• LyricHandle - a reference to a further section containing more information on the lyric properties of the current note
• VibratoHandle - a reference to a further section containing more information on the vibrato properties of the current note

[edit] h#XXXX

These sections contain information referenced from other properties (the various XXXXHandle properties).

[edit] IconHandle

• IconID - contains the unique ID of the current singer
• IDS - the name given to the current singer ("Miku", for example)
• Original - the original MIDI Program Change command issued to the current singer
• Caption
• Length
• Language
• Program - the current MIDI Program Change command issued to the current singer

[edit] LyricHandle

• L0 - this is a comma-separated list of five values, not all of which are known. What is currently known is that the first value is the lyric and the second the phoneme.

[edit] VibratoHandle

• IconID
• IDS - as with IconHandle above, this is the name given to the current vibrato setting ("normal", for example)
• Original
• Caption
• Length - the length of the vibrato
• StartDepth - the starting vibrato depth
• DepthBPNum
• StartRate - the starting vibrato rate
• RateBPNum
