If immediately after the note comes character ‘#’, then the note is higher in pitch by a

semitone (sharp). If immediately after the note comes character ‘&’, then the note is lower in

pitch by a semitone (flat).

- Pause: Character space (ASCII 20h).

After a note or pause there can be one or a few bytes, which specify the duration. Valid are

characters from ‘0’ to ‘5’, they have the following meaning:

‘0’ basic duration of a

note/pause

‘1’ basic duration * 2

‘2’ basic duration

* 4

‘3’ basic duration

* 8

‘4’ basic duration

* 16

‘5’ basic duration

* 32

If there are a few durations one after another they are summed up.

• Going to higher scale: character ‘+’.

• Going to lower scale: character ‘-‘.

• Specifying tempo: character ‘^’, followed by a number. The number specifies the

percentage: duration of notes and intervals to basic duration. Values:

‘1’ 200 %

‘2’ 175 %

‘3’ 140 %

‘4’ 120 %

‘5’ 100 %

‘6’ 80 %

‘7’ 60 %

‘8’ 50 %

‘9’ 40 %

- Return to scale 1 (it is default). Character ‘@’. Tone ‘La’ in it is 440 Hz.

It is recommended that the data ends with ASCII code 03h, although any other non-printing

character will also stop the command.
