Little Sound Dj (LSDj) is a music tracker for the Nintendo Game Boy and Game Boy Color that runs natively on the system or in an emulator. It leaves nearly all of the Game Boy's music capabilities in the hands of the user—for this reason, it is one of the most popular Game Boy music tools. The program also sees frequent updates and has been maintained diligently for nearly two decades. It is a paid program, but demo ROMs are available if you wish to try it out.


LSDj allows the user to use all four of the Game Boy's sound channels to their fullest extent. There are two square waves, one variable-waveform/sample channel, and one noise channel (for more information on sound, see GameBoy (format)).

Instruments can be customized easily and even feature parameter automation via a feature called "tables". These allow for custom volume macros, custom arpeggios, and extra effect commands. Tables can be tied to an instrument or triggered with an effect command.

LSDj is also one of the few Game Boy music programs to support samples. It comes with samples of popular drum-kits built in, as well as a speech synthesizer. Up to two samples can be played at one time. If you don't care for the samples that are built in, additional samples can be added to your ROM with the LSDPatch
tool. This tool also allows you to patch in custom fonts and palettes if you like.

Two Game Boys running LSDj can be linked together using a link cable to double the amount of channels. In addition to this, MIDI input and output is supported—however, this feature requires an extra device such as an Arduinoboy
and only works on real hardware. This feature can be used to sync to different music programs or music hardware.

Step by step install (Windows emulator)

Here is a fast and efficient way to install LSDJ be ready to render easily if you are running windows.


1) Download the last stable official ROM
2) Download BGB emulator
, 64 bit or not depending of you PC
3) Extract it. The sofware doesn't need installation, so just add it to you taskbar or create a shortcut
4) Run it (the .exe file), and right click on the screen. Then "Load ROM" and open your LSDJ ROM!

Setup (recommended):

5) Right click, go to "Options" > "Joypad", check the box "configure extra buttons" then click configure keyboard (or game controller if you have one working)
The extra buttons allow you to record audio and/or video! Be sure to define them. You can also record the different channels separately!

Remember it is an emulator, so saving inside LSDJ is not enough, you have to save the state of your emulator. Hopefully, there is an automatic save, use use F2 (or your save shortcut if you have a different one) to save often.
