Little Sound Dj (LSDj) is a Game Boy music sequencer used by video game musicians, Grammy winners, and chiptune virtuosos over the world. It is regularly praised for being intuitive, fast and fun.

More information on LSDj and other related things can be found at Little Sound Dj Wiki.

Features

  • 4-channel, 4-bit Game Boy sound.
  • Dual sample playback.
  • Waveform synthesizer.
  • Speech.
  • 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.
