Namco C219

Namco C219 is a 16-channel PCM sound chip that's a lot like C140, but has a noise generator, surround effect and a different µ-law curve.

this chip features:

  • stereo soft panning
  • accepts either 8-bit PCM or proprietary 8-bit µ-law compressed PCM samples

sample memory notice

this chip is rather unique when it comes to sample memory. be sure to read this notice.

the channels are in groups of four. a sample bank (128KB) may be selected for each group. if a sample that is on a different bank plays in a group, the group is switched to that bank, and other channels will be silenced.

effects

  • 11xx: set noise mode.
  • 12xy: set invert mode.
    • if x is 1 or higher, surround is enabled.
    • if y is 1 or higher, invert is enabled.

info

this chip uses the C219 instrument editor.
