(iii) Duration specification
The duration specification determines the length of the specified note. Dura-
tions from 1/32 to 1 are specified as numbers from 0 to 9 as shown below.
(When R is specified, the length of the silent interval is determined.)

The following options can be defined in the <melody> specification:
n=integer Default ry
value value Desceos
On O0to6 2 Sets the current octave. The frequency of A is |
440Hz if n=2.
Nn 0 to 83 Specifies the note directly through the cor-
responding note number rather than through thi
octave number and note name. The values of n
are listed in the table on the following page.
Values NO to N8 means rest.
—-
Tn lto7 4 Sets the tempo in the same way as the TEMPO
statement.
Vn 0 to 15 15 Sets the sound volume, The volume is maxi-
mum when n=15 and no sound is generated
4 when n=0.
Sn 0to7 8 Sets the envelope pattern (sound waveform).
For the values of n, see the figures for enve-
I lopes on the following page.
Mn 1 to 255 255 Always used with the S parameter to specify the
rate at which the envelope pattern is to change.
1 =approx. The rate is maximum when n= 1 and decreases.
10m/s The slope of the envelope becomes slower as the
value of n increases. Values of Mn which are
too large may generate inaudible sound depend-
ing on the envelope pattern.
Ln 0to9 5 Sets the length of the note. |
