Gamble Kid Recording

Gamble Kid is a virtual instrument for Native Instruments Kontakt, giving you the classic sound of a very famous Japanese 8-bit handheld console from 1989 (GB DMG-01).

The original GB sound chip features four sound channels: Square (CH1/CH2), Wave (CH3) and Noise (CH4). To enable MIDI support a self-built “Arduinoboy” MIDI interface was used in addition to the soft­ware mGB V1.3.3 running on the GB. To reduce audio noise the GB was modified with an addi­tional audio output bypassing the internal speaker (“Pro Sound Mod”). The audio was recorded using an A-Designs P-1 microphone preamp.




  • Square channel: Four different pulse widths with 16 different pitch sweeps (= 64 total), ranging from C1 – F6 each
  • Wave channel: 16 different shapes, ranging from C0 – F5 each
  • Noise channel: each note features a different noise sound (ideal for 8-bit drum sounds), ranging from C0 – G6
