# 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 recommended. use Sample type instruments instead.**
## info
this chip uses the [PC Engine](../4-instrument/pce.md) instrument editor.
## channel status
when enabled, channel status will show an additional icon representing the noise mode of the currently playing note:
- ![noise mode off](status-PCE-noise-off.png) noise mode off
- ![noise mode on](status-PCE-noise-on.png) noise mode on
