Harlem POKEY

from Shakebit by Inverse Phase



Track written in: Custom environment and Music ProTracker 2.11
Chip found in: Atari 400, 800, XL, XE, 5200, many Atari arcade machines
Other names for chip: CO12294

Channels: 4 with selectable type for each (square/distortion/whitenoise)
4-bit volume, 8-bit pitch
Quirks: can combine two 8-bit channels to make one 16-bit channel for better pitch control.

Designed by Doug Neubauer, Atari's "Potentiometer Keyboard" chip listened for paddle and keyboard input on lots of different 8-bit Atari systems. It also had sound hardware crammed into it, and produces sound very similar to (but better than) Atari's TIA chip. It was in basically every Atari system EXCEPT the 2600 and 7800 (though it was included on-cartridge with a few 7800 games). Because of the lower bits on the frequency control, some tones are off-pitch.
