Well I hooked up the 2600's Audio output to my C-64's Pitch-2-Midi converter
and booted the digital tuning meter.
It drove the damn thing CRAZY on everything below middle C. So then I had
to play it by ear compairing the notes to a sine wave on one of my keyboards.
Here's how the tones produced on a 2600 sound to the human ear.
Granted, I've only mapped this out for Sound Type #1. I'm assuming that the
fequency proportions are the same for all the other sounds.
Anyways, here's what I came up with...
ATARI 2600 Sound Map
SOUND TYPE: 01

PITCH 00: C 4 -- Slightly Sharp
01: C 3 -- Close
02: F 2 -- Slightly Sharp
03: C 2 -- Close
04: G# 1 -- Sharp
05: F 1 -- Close
06: D 1 -- Very Sharp D# -- Very Flat
07: C 1 -- Close MIDDLE C
08: A# -1 -- Close
09: G# -1 -- Close
10: F# -1 -- Very Sharp G -- Very Flat
11: F -1 -- Close
12: E -1 -- Slightly Sharp
13: D -1 -- Very Sharp
14: C# -1 -- Sharp
15: C -1 -- Close
16: B -2 -- Close
17: A# -2 -- Close
18: A -2 -- Sharp
19: G# -2 -- Sharp
20: G -2 -- Very Sharp
21: F# -2 -- Very Sharp
22: F -2 -- Very Sharp F# -- Flat
23: E -2 -- Extremely Sharp F -- Slightly Flat
24: E -2 -- Sharp
25: E -2 -- Slightly Flat
26: D# -2 -- Close
27: D -2 -- Very Sharp D# -- Flat
28: D -2 -- Slightly Flat
29: C# -2 -- Slightly Sharp
30: C# -2 -- Flat
31: C -2 -- Slightly Sharp
Hope this is helpful. The higher you want to have the pitch, the fewer notes
You get to choose from. And with all these funky 1/4 and 1/8 tones, you
can get some pretty neat east-indian music happening.
CRACKERS
(The hills are alive with the sound of the 2600 from hell!!!!!!!!!!!!!)
