So, I highly doubt there exists a "mode 2".
No, there doesn't. It's much simpler than Charles describes.
Never seen this problem before - and looking at the shots, and the description of what it's doing/what's happening... I have no idea at all why this wouldn't work in Fusion already. It must be ...

Personally, the think that irks me the most is the behaviour when the effective attack rate is 62 or 63. If it was just a matter of forcing the attenuation directly to 0 when the attack phase is entered with these rate values, well, that's one thing, but the "stalling" behaviour when changing to ...

Ahh, but remember that the attenuation isn't moving past 0x200 during a repeating SSG-EG wave.
Ah, this is what I meant, but I didn't explain it very well :)
I was assuming the attenuation starts at 0x3FF, and is decremented until it hits 0x200 - at which point it will immediately switch to decay ...

The samples are averaging together, which is why you're being left with a regular sine wave at mid-level.
I did consider that, but since the sample rate is not divisible by the hardware output rate, I would have expected to see some clear distortion rather than an almost perfect wave - I can see ...

Hmm, that is strange. It looks like the one running at the higher frequency has some additional noise on the output signal. I'll take a look.
It's probably writing to the DAC at around the same time the chip is trying to read it.
I can't say I've done very thorough tests on this. I generally ran ...

Wow, huge post :) Kind of odd that you would post this right now. I have a ton of SSG-EG samples I did years ago, but I lost the test ROMs that created them, so I didn't know what I was looking at. This weekend I found them and spent most of it looking into this again. I'll read your post properly ...
