The HuC6280 is the sound chip used in the PC Engine/TurboGrafx-16, a console from NEC that, depending on region:
  • Attempted to enter the fierce battle between Nintendo and Sega, but because its capabilities are a mix of third and fourth generation, it failed to last long (US and Europe), or
  • Was Nintendo’s most fearsome rival, completely defeating Sega Mega Drive and defending itself against Super Famicom (Japan).
It has 6 wavetable channels and the last two ones also double as noise channels. Furthermore, it has some PCM and LFO capabilities!

Channel Configuration

  • 6 wavetable channels
  • Channels 5 and 6 support noise mode
  • PCM support
  • LFO functionality (uses channel 2 output to modulate channel 1 frequency)

Effects

EffectDescription
10xxChange wave
11xxToggle noise mode (channels 5-6 only)
12xxSetup LFO
00: LFO disabled
01: LFO enabled, shift 0
02: LFO enabled, shift 4
03: LFO enabled, shift 8
When LFO is enabled, channel 2 is muted and its output is passed to channel 1’s frequency
13xxSet LFO speed

Channel Status Icons

When channel status is enabled in the pattern view, the following icons are displayed: Noise mode (channels 5 and 6 only):
  • Noise mode off
  • Noise mode on

Chip Configuration

The following options are available in the Chip Manager window:
  • Pseudo-PAL: Run the chip on a PAL clock. Such a configuration has (probably) never existed, despite a planned official PAL version of the PC Engine.
  • Disable anti-click: Waveform switching requires a phase reset, which may cause clicks. Furnace uses a wave-position predicting algorithm to minimize these clicks. Check this option to disable the feature.
  • Chip revision: Sets the chip revision. HuC6280A has less pops.

Instrument Editor

This chip uses the PC Engine instrument editor.
