Beep8 Music Editor

Beep8 generates music with javascript live in the web browser. It uses a simple notation to define notes. The music editor allows you to create and edit music for your Beep8 games.

Music Structure

The music is structured as a text string. The first line is 2 numbers, tempo (milliseconds per note, default=125) and note duration (value 0-200, default=50) separated by a dot. This can be removed to use the defaults.

The tempo is the speed of the music, the note duration is the how long each note is held before changing. These options are optional length of each note in milliseconds.

The remainder of the music is the different channels, this is where the music happens.

Channel Structure

Beep8 Supports up to 4 channels. More than this may cause an error.

If a channel is shorter than other channels it will leave a pause and play again the next time the music loops.

Instruments

The first number on each channel is the instrument number. The instrument number is a number from 0 to 7. The instruments are:

• 0: Piano (default)
• 1: Piano 2
• 2: Sine
• 3: Sawtooth
• 4: Square
• 5: Triangle
• 6: Drum
• 7: Soft Drum

Notes

The notes are placed between 2 pipes to define the start and end of the channel. The notes will play in order, spaces will be gaps. Dashes will hold the note for the sustain time.

The notes are represented by letters from A to z as shown below. This allows us to use the same note in different octaves.
