This a little different. This is some software to help people create some music. A house hold name L.S.D.J.(little sound dee jay) you can either load this on a flash cart or play it on an emulator. I am sure all of us here are able to find an emulator somewhere.
The basic idea is to transform a plain Game Boy/Game Boy Color into a full-fledged music workstation.
The sequencer of Little Sound Dj has a very open structure. It was designed to leave all the musical possibilities of the Gameboy in the hands of the user. The system can be said to be both simple and complex; it has a slight learning curve, but when learned, it is possible to transcribe a complete Bach piece to it on less than one hour.
The Gameboy sound chip offers four channels with 4-bit sound. Custom waveforms can be created by free-hand drawing, or by using a subtractive synthesizer with resonant filters. For extra versatility, Little Sound Dj also contains a quite powerful arpeggiator, which possibilities go far beyond the classic C64-style chords.
Sample-wise, Little Sound Dj boasts a set of 59 phonems 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.
It is possible to 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 instructions in manual, or purchased here. Even MIDI sync is possible, if you are ready to build your own LSDj Midi Interface.
