#X text 34 93 First compare this phase modulation example with the
ring modulation example from the section on processing (patch 51).
Here we choose a convenient \, fixed modulation frequency and consider
the effect of changing carrier frequency and modulation index. It's
exactly as if the carrier frequency were a ring modulation frequency.
;
#X text 33 331 Next we'll look at two techniques for sliding a formant
frequency without losing harmonicity.;
#X text 33 191 Using either method we can synthesize the hat-shaped
spectra called "formants." However \, if you try to move the formant
up or down in frequency \, you'll lose harmonicity \; the partials
are only integer multiples of the fundamental \, 172.266 \, when the
carrier is an integer multiple. To hear this \, set index to 20 and
carrier frequency to zero \, and scroll carrier through integers. Then
shift-drag on the carrier frequency to change it in hundredths. Presto
\, inharmonic sounds...;
