|
|
|
|

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).
