Mixer
Mixer
The Mixer makes it it possible to combine the outputs of
Oscillators 1,2 and 3, the Noise source, the Ring modulator and
the external Audio Input. The ability to mix together any or all of
these sound sources makes easy to create complex timbres.
Osc 1 & 2 Knob
Controls the volumes of the two Oscillators. Fully anticlockwise
results in no signal. In this position and with all the other Mixer
levels turned down, there will be no audio output. Turning clock-
wise, Oscillator 1 will be introduced. At the 1 & 2 position both
Oscillators will be of equal volume. Fully clockwise results in
Oscillator 2 only being heard.
Osc 3 Knob
Controls the volume of Oscillator 3. Fully anticlockwise results
in no signal. Fully clockwise results in full volume for this
Oscillator.
Source Switch and level Knob
Selects which sound source the level knob will control.
In the NOISE position it controls volume of the White Noise
Generator. White Noise is useful for creating sound effects such
as Wind.
In the RING position it controls the volume of the Ring
Modulator. Ring Modulation is useful for creating harder Metallic
tones.
In the EXT position it controls the volume of the External audio
input signal. This signal can be processed by the filter,
envelopes and effects.
Note: All three sound sources may be used simultaneously and
if they are, it may be necessary to reduce the program level
(see page 14).
