modulation (FM) since their inception.  Low frequency FM produces nice vibrato effects, and audio rate FM creates interesting timbres.  But exponential FM alters the perceived fundamental frequency of an oscillator; linear FM is required to alter the timbre while staying on pitch.\u003c\/p\u003e\n\u003cp\u003eWhen we use FM, we call the source of the modulation the modulator, and the oscillator being modulated is called the carrier.\u003c\/p\u003e\n\u003cp\u003eIn the early 1970’s, John Chowning discovered using digital oscillators that linear FM through the zero point (so the carrier actually reversed its oscillation) produced very diverse and pleasing timbres.  Yamaha further developed this technology, but while Yamaha continued to call their implementation “FM”, they actually were using Phase Modulation.  Also worthy of note, Don Buchla heard Chowning say that you couldn’t do “through zero” FM with an analog circuit, so Don did just that with his Music Easel’s Complex Oscillator.\u003c\/p\u003e\n\u003cp\u003eLet’s look at some oscilloscope photos to understand the difference.  If I frequency modulate a sine wave with another sine wave, the ‘scope shows us the effect on the waveform.  (The modulator is on the bottom in blue, the carrier in yellow on the top):\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" class=\"aligncenter size-medium wp-image-1333\"

modulating the carrier’s frequency, have the modulating oscillator modulate its “phase.”  What this means is that the modulator is directly changing the location in the carrier’s waveform, rather than changing the rate that the carrier oscillates by moving along through its waveform.  Here’s what a sawtooth phase modulated by a pulse looks like.  When the pulse goes high, the carrier skips ahead to a higher point in the sawtooth ramp; when it goes low, it skips back to a lower point.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" class=\"aligncenter size-medium wp-image-1337\"
