Noise, Ring Modulator And Feedback - Yamaha PLG150-AN Bedienungsanleitung

Analog Physical Modeling Synthesis and the PLG150-AN Tone Generator
VCO1
Slave oscillator.
Determines the timbre
or tone.
Oscillator Sync
VCO2
Master oscillator.
(This determines the pitch.)
Using Oscillator Sync to lock VCO 1 to VCO2
This method is the same as on conventional analog
synthesizers. The sound quality can be changed by
giving VCO 1 and VCO 2 different pitches.
FM
FM uses the wave of one oscillator (called the "modulator") to periodically change the pitch or fre-
quency of another oscillator (called the "carrier").
The FM generated sound is output by the carrier, and the type and amount of harmonics that are added
to the sound differs depending on the ratio of the modulator and carrier frequencies.
On the PLG150-AN, the following can be used as the modulator: VCO 2, LFO, and each EG. The
carrier is fixed to VCO 1.

Noise, Ring Modulator and Feedback

In addition to the VCO 1 and VCO 2 oscillators, the PLG150-AN includes a Noise oscillator, plus
Ring Modulator and Feedback controls. The levels of these five sound sources can be freely mixed,
giving you a wide range of sonic possibilities and comprehensive sound shaping control.

Output of the
basic sound.
Avoid making drastic changes to Feedback, or setting the Feedback level to values at or near
the maximum. Doing so could damage your speakers (and your ears!). If you hear any strange
or unusual vibrations in your speakers as you are adjusting the Feedback level, immediately
turn Feedback down.

VCO2
Using Oscillator Sync within VCO 1
This method is unique to the PLG150-AN. Since
VCO 1 and VCO 2 are independent, you can still use
Oscillator Sync to get more harmonics, yet layer VCO
1 and VCO 2 to produce sound of even greater
complexity and richness.
