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

Maximum sample length is 131072, and loop start and end points must be even numbers.
