# SegaPCM

16 channels of PCM? no way!

yep, that's right! 16 channels of PCM!

a chip used in the Sega OutRun/X/Y arcade boards. eventually the MultiPCM surpassed it with 28 channels, and later they joined the software mixing gang.

## 5-channel SegaPCM

Furnace also has a five channel version of this chip, but it only exists for DefleMask compatibility reasons (which doesn't expose the other channels for rather arbitrary reasons).

## effects

- `20xx`: **set PCM frequency.**
  - `xx` is a 256th fraction of 31250Hz.
  - this effect exists mostly for DefleMask compatibility; it is otherwise recommended to use Sample type instruments.

## info

this chip uses the [SegaPCM](../4-instrument/segapcm.md) instrument editor.
