It's nothing but an oscillator with vibrato -controlled by another "modulation" oscillator. First \, to understand -the patch \, set carrier frequency to 400 or so \, modulation frequency -between 5 and 10 \, and try modulation index values between 0 and 400 -\, say. You'll hear a sine wave with vibrato.; -#X text 55 526 The component frequencies are equal to the carrier frequency -\, plus or minus multiples of the modulator frequency.
