Some more digging later: In FM2/3, the new and old modes diverge more and more the higher the percent. Same percent is always closest to a null, but at 50 they null to about -50 dB, at 100 only to -12, and once you get noisy they differ too much to null at all. Sine doesn't seem to do that. |

1. Actually store last value 0 (duh) and 2. apply the squaring etc at the same place as FM2 Closes surge-synthesizer#7152

...correct? Borked? Hard to say.
But this is true: (sine old fb x) - (sin new fb 2 x) = 0
Or in other words the new one gives exactly the same result as the old at half the percent value.
In FM2 and 3 this is not true. The new and old modes never subtract to silence.
Investigation needed.
