It's a basic FM with a single modulator-(envelope)->carrier setup, and can be extended with extra voices and detuning to run 2-3 or more operators.

Syntax: `new synth fm index() ratio() fmShape()`

A new effect is added in @mercury . It is a Karplus-Strong effect, based on a lowpass feedback combfilter, that can be tuned to the notes of your scale. The feedback can be positive (odd+even harmonics) or negative (odd harmonics, for a flute-like sound).
