Add PADsynth algorithm for fat pad/string sounds. Gaussian distribution is probably the best one. There are two possible implementation types:

Increase the FFT frame size by 16-64x and add extra waves between harmonics. The FFT will probably still be very fast even with a larger window. A resolution of 64x should be enough, but less will possibly work as well.
Perform 2-16 extra FFTs in which each spectrum the harmonics are scaled according to Gaussian amplitude for the specific detune. Then add the detuned waves in the time domain.

Solution 2 is probably faster for a few extra waves, while solution 1 is probably faster for many extra waves.
