Welcome to Little Sound Dj, the ultimate music program for Game Boy and Game Boy Color!


Little Sound Dj turns a plain Game Boy/Game Boy Color into a full-fledged music workstation.


The sequencer puts all musical possibilities of the Game Boy in your hands. The design is simple but deep; when mastered, it is possible to transcribe a complete Bach piece to it in less than one hour.


The Gameboy sound chip offers four channels with 4-bit sound. Create your own waveforms by free-hand drawing, or using the subtractive synthesizer. The powerful programmable tables with 18 different commands allow you to tweak the sounds in any direction that can be imagined.


Sample-wise, Little Sound Dj boasts a set of 59 phonemes for programmable speech. Besides that, it also features drum kits sampled from machines TR-606, TR-707, TR-727, TR-808, TR-909, CR-78, CR-8000, KR-55, DR-55, DR-110, DMX, Drumulator, RhythmAce, TOM and LinnDrum.


Use a link cable to sync two Game Boys; great for party fun or for added polyphony! LSDJ can also be synced with Nanoloop or Korg Volca/Monotribe. Korg-to-Game Boy cables can be built using simple instructions in the manual. Even MIDI sync is possible, if you are ready to build your own LSDj Midi Interface.

Official Little Sound Dj cartridges have not been produced for a very long time. There are no definite plans to start again, for several reasons. Sorry for the inconvenience!

If you still want to use the software, an option is to purchase access to the full-version ROM image file for 0.01 USD + a voluntary donation. The ROM image can then be used either with a Game Boy emulator (on PC, Mac or PSP) or a Game Boy backup device (e.g. e-merger, transferer, xchanger, pc-linker). Backup devices can be bought for example at HK EMS (on request), Console Goods, Kitsch-Bent, noiseandroid, DMGS-R-US, Retro Towers, Nonfinite or Krikzz.

It is really recommended to get a backup device, so you can backup your songs and protect yourself against data loss. Transferer cartridges are powered by a clock battery that eventually WILL run out (even if it can take many years if you're lucky).

More information on how to put the program on a cartridge can be found here and here.

Donation through Bitcoin possible on request!


The latest demo ROM image and documentation can be downloaded here. Feel free to try it out with a decent Game Boy emulator; some good alternatives are BGB (best emulator, PC only), VisualBoyAdvance-M (PC/Mac), and RIN (PSP).

Keep in mind that sound emulation can never be 100%, mostly because the low-grade hardware used in Game Boys adds some characteristic noise. Little Sound Dj should however run OK with the emulators listed above. The recommendation should be to try out the demo version with some different emulators until you find one you like.
