Raw Blame History

PC Engine/TurboGrafx-16

a console from NEC that 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.

it has 6 wavetable channels and the last two ones also double as noise channels. furthermore, it has some PCM!

effects

  • 10xx: change wave.
  • 11xx: toggle noise mode. only available in the last two channels.
  • 12xx: setup LFO. the following values are accepted:
    • 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.
  • 13xx: set LFO speed.
  • 17xx: toggle PCM mode.
