PC Engine/TurboGrafx-16

a console from NEC that, depending on a 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!

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 LEGACY sample mode.
• this effect exists only for compatibility reasons! its use is NOT recommented. use Sample type instruments instead.
