# 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 for mostly DefleMask compatibility - it is otherwise recommended to use Sample type instruments.
