-#X text 126 349 Now we introduce a second modulator oscillator. The
-carrier is on the 8th harmonic and the two modulators are at 2 and
-3 times the fundamental. When either index of modulation is zero \,
-changing the other index gives the familiar 2-operator FM result. But
-if index2 is nonzero (try around 10 \, for example) then sliding index1
-upward from 0 introduces sidebands around each of the sidebands.;
