Audio Mixer

NOISE GENERATOR

The noise generator produces white noise which contains all audible frequencies at equal

volume. This is like the hiss you hear between radio stations. The signal is available for

filtering via the Noise/Sub mixer control. Noise would be used for sound effects such as

breath, wind, percussion, etc.

SUB OSC

A sub oscillator is a signal taken from a VCO that is then taken down one or more

octaves below the source VCO. In this case the Sub is taken from VCO1, and is one

octave lower. Sub Osc is used typically for creating deeper and more powerful bass

sounds. The Sub Osc waveform is a square wave.

MIXER

The mixer is used to bring various audio source signals together for filtering. There

are 3 mixer controls.

SAW/PULSE VCO1 LEVEL

Turning the control clockwise in increasing amounts sends VCO1s pulse signal to the

mixer. Turning the control anti-clockwise in increasing amounts sends VCO1s

sawtooth wave signal to the mixer. In a central position no signal is sent from VCO1

to the mixer.

SAW/PULSE VCO2 LEVEL

Turning the control clockwise in increasing amounts sends VCO2s pulse wave signal

to the mixer. Turning the control anti-clockwise in increasing amounts sends VCO2s

sawtooth wave signal to the mixer. In a central position no signal is sent from VCO2

to the mixer.

NOISE / SUB LEVEL

Turning the control clockwise in increasing amounts sends the Sub Osc signal to the

mixer. Turning the control anti-clockwise in increasing amounts sends white Noise to

the mixer. In a central position no signal is sent from the Noise generator or Sub Osc

to the mixer.
