Appendices
Pan (control change number 10)
This message controls the stereo position of a Part. (p.27)
Hold (1) (control change number 64)
This message conveys the up/down movements of the damper pedal, causing the
currently sounding notes to be sustained. When a Hold On message is received,
notes will be sustained. In the case of decay-type instruments such as a piano, the
sound will decay gradually until a Hold Off message is received. In the case of sus-
tain-type instruments such as an organ, the sound will continue sustaining until a
Hold Off message is received.
Sostenuto (control change number 66)
The sostenuto pedal on a piano sustains only the notes which were already sounding
at the moment the pedal was pressed. The Sostenuto message conveys the move-
ment of this pedal. When Sostenuto On is received, only the notes which were al-
ready on at that moment will be sustained. In the case of decay-type instruments
such as a piano, the sound will decay gradually until a Sostenuto Off message is re-
ceived. In the case of sustain-type instruments such as an organ, the sound will con-
tinue sustaining until a Sostenuto Off message is received.
Soft (control change number 67)
The soft pedal on a piano softens the tone during the time the pedal is pressed. The
Soft message conveys the movement of this pedal. When Soft On is received, the cut-
off frequency will be lowered, causing a softer sound. When Soft Off is received, the
previous sound will return.
Reverb Send Level (control change number 91)
This message adds a reverb effect to the Part. (Reverb Level p.40)
Chorus Send Level (control change number 93)
This message adds a chorus effect to the Part. (Chorus Level p.42)
Delay Send Level (control change number 94)
This message adds a delay effect to the Part. (Delay Level p.44)
Portamento (control change number 65)
Portamento Time (control change number 5)
Portamento Control (control change number 84)
Portamento is an effect that creates a smooth change in pitch between the previously
played note and the newly played note. When a Portamento message is received, the
portamento effect will be turned on or off. Portamento Time controls the speed of the
pitch change. Portamento Control specifies the Source Note number (the previously
played note).

If applying a portamento
effect to the currently
played note through to a
lower note, the range of the
effect may be limited (to
about two octaves).
