The Nintendo Entertainment System (NES) musical chipset is limiting in so many ways, it is both a blessing and a curse. The medium makes it very difficult to develop a sound that’s unique and engaging with limited duty cycles and volume envelopes, but it’s very rewarding to creatively solve this puzzle and compose music that’s engaged gamers for over thirty years.

Keeping the inherent restrictions in mind, this sixth album by Zi uses only four instruments. Each instrument uses one of the 2a03 chip sound processor duty cycles (12.5%, 25%, 50% and 75%) at full volume across the four available tracks (Pulse 1 & 2, Triangle, and Noise – no DPCM or sample track used). Using Famitracker’s volume column and effect commands, Four extracts a melodic sonorousness from the rigid protocol imposed on the NES chipset.
