@CODMarioWarfare As for how it works, try setting famitracker looped playing something like a scale on the FDS channel and set the wave table and the modulation table to sine. Next, put the modulation depth on something like 25 and then start cranking up the modulation frequency and listen to what happens.
I see what you're talking about in Famitracker now. I always saw it as a way of doing vibrato, but the rate does go conspicuously high for that.
I suppose this could be considered FM-synthesis, but not in any normal way (hence terming it primitive I guess) as the modulation rate doesn't scale with the note and so the timbre for every note is different (because the ratio between the frequency of the note and the frequency of the modulation isn't constant).
@eyeball226 Wikipedia: "and also included additional sound hardware featuring primitive wavetable synthesis and FM synthesis capabilities."

Famitracker has FM settings for FDS. I'm not sure how it works, as it hardly seems to do anything. My guess is that it either modulates the wave or replaces the wave.
@CODMarioWarfare I'm glad someone else is trying to stop the proliferation of the myth that the FDS had FM synthesis. As you said, it's just a (64 x 64) wavetable.
Here are the tracks in order -
1. Title
2. Overworld
3. Enemy Encounter
4. Unused Track #1
5. Town
6. House #1
7. House #2
8. Got Magic

@CODMarioWarfare Really? Because I can't find any real evidence for that at all. The VRC7 had FM, you're not thinking of that are you?
Do you mean there was a second channel that used FM synthesis, or that it was capable of FMing the wave table output?
There's no mention of it here for example: nesdev[dot]parodius[dot]com/FDS.txt

@CODMarioWarfare Cool, I didn't know that.

Also, it's not FM; they're custom waveforms.

@eyeball226 The Genesis had stereo sound through coaxial.

@CESkootchy Ah, we didn't have that. We had NICAM instead. =/
