• Sync options (analog, Game Boy, MIDI, VST).

User guide

Getting started

The Game Boy sound chip has four channels, each with 4-bit resolution.

• Pulse Channel 1 Square wave with envelope and sweep functions.
• Pulse Channel 2 Square wave with envelope function.
• Wave Channel Soft synthesizer, sample playback and speech synthesis.
• Noise Channel Noise with envelope and shape functions.

Little Sound Dj starts with the song screen, displaying four sound channels: PU1, PU2, WAV, and NOI. The D-Pad allows cursor movement between channels. It has nine screens arranged in a map, with the most useful ones in the middle row, used for sequencing in a tree-structure: song, chain, phrase, instrument, and table screens.

Press Select+D-Pad to switch screens, and for in-built help, go to the project screen and tap A on HELP. The help screen provides button presses and command lists for different screens.

To create music in Little Sound Dj, navigate to the song screen, select the PU1 column, and tap A to create a new chain "00". Edit the chain by entering the chain screen (Select+Right) and insert a new phrase (A). Move to the phrase screen, enter notes by pressing A in the note column (e.g., C-2). Press Start to play the phrase. Modify the notes using A+D-Pad. Delete notes with A while holding B.

To enhance the pulse sound, move to the instrument screen (Select+Right) and experiment with ENV. and WAVE fields (A+Left/Right). The TYPE field sets the instrument type (PULSE, WAVE, or NOISE). For sampled drum kits, switch to the wave channel, create a new chain and phrase, and set the instrument type to KIT. Enter drum sounds in the phrase screen. To add new chains and phrases, tap A twice on an empty step in the song or chain screen.

Number system

Little Sound Dj uses hexadecimal numbers, which have 16 unique symbols: the digits 0 to 9, followed by the letters A to F. As an example, let’s print a table of numbers - first with decimal digits, then with hexadecimal digits:

    Decimal  1  2  3  4  5  6  7  8  9 10
Hexadecimal  1  2  3  4  5  6  7  8  9  A
    Decimal 11 12 13 14 15 16 17 18 19 20
Hexadecimal  B  C  D  E  F 10 11 12 13 14

Hexadecimal is used to save screen space, representing every byte value with two digits (0 to FF). Negative numbers wrap around, so FF can represent -1 or 255.

Troubleshooting

Does your cartridge not start, crash, or act strange in other ways? Here are some things to try.

• To avoid losing songs, always use fresh batteries. Replace as soon as the red light on your Game Boy gets faint, or the screen gets dim.
• Clean cartridge pins using a cotton swab and alcohol.
• Re-insert the cartridge a couple of times to remove oxide.
• Make sure that the cartridge is firmly plugged in. Sometimes it can help to put a piece of tape on the cartridge to give it a snug fit.
• Do a full reset of the cartridge memory. This is done by pressing Select+A+B on the LOAD/SAVE FILE button in project screen.
• Certain Game Boy Advance/Nintendo DS cartridges do not work with Little Sound Dj. If you have problems with such a cartridge, try one of the Little Sound Dj builds named "Goomba".
• Search for help on the Little Sound Dj Wiki or ask in the Facebook group.

Compatibility

The recommended and most reliable way to use a ROM image is through Game Boy emulators like BGB (for Windows) and Sameboy (also compatible with Mac/Linux using Wine). Additionally, hardware emulators like RG300, BittBoy, and Odroid-GO are available.

To use LSDj on an original Game Boy, place the ROM image on a reprogrammable flash cartridge, there are many cartridge models available for this purpose.
