9.8.1 Audio String Format
The audio strings found under the header must conform to a specific
syntax. If the audio string syntax is invalid, an error message will be displayed
when the MCNRCD software attempts to play the audio string.
The audio strings use the following syntax:
Set Octaves and Play Tones
On
Sets current octave (n = 0-6)
< or > Up or down one octave
Nn
Plays note n (n = 0-84, 0 is a rest)
A-G Plays A, B, ..., G in current octave (# or + = sharp, - = flat)
Set Tone Duration and Tempo
Ln
Sets length of a note (L1 is whole note, L4 is quarter note, etc.)
n=1-64
MS Each note plays 3/4 of length
MN Each note plays 7/8 of length
ML Each note plays full length
Tn Sets number of quarter notes per minute (n = 32-255, 120 default.
Pn Pause for the duration of n quarternotes (n = 1-64)
Table 6 shows the notes that can be played in an audio string, along with the
frequency of the notes.
The default MCNRCD.CFG file shown in Figure 32 defines three audio output
strings. The strings play the following tones:
Audio String # Output Tones
1 3 beeps, each at 3951 Hz
2 a 1760 Hz beep followed by a 622 Hz beep
3 3 beeps, each at 2093 Hz
