LSDJ is a software that transform a plain Game Boy/Game Boy Color into a full-fledged sequencer.
The sequencer of Little Sound Dj has a very open structure. So a lot of things is possible and LSDJ is 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, two pulse wave channels one DPCM (sample data) channel and one noise channel. 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! If you want to, you can sync LSDJ with Nanoloop. MIDI sync is possible too, if you are ready to build your own LSDj Midi Interface.
