Main Features and Operation
Mixer Section
LFO 1 DEPTH Knob
Controls the amount of pitch modulation to an Oscillator from LFO 1. It
controls how much above and below the basic pitch the Oscillator reg-
ularly rises and falls. If the LFO is set to Triangle wave and the LFO’s
speed knob is above the centre of its range, this will produce a vibrato
effect. Other effects like a siren or sea gull cry are possible with more
extreme settings.
Other functions associated with the Oscillators can be found in the
Oscillators Menu. See Pages 23 - 24.
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 it easy to create complex timbres.
OSC 1, OSC 2 & OSC 3 Knobs
Controls the volumes of the three 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. Fully clockwise results in
full volume for this Oscillator.
SOURCE Button and LEVEL Knob
The SOURCE button selects which sound source the LEVEL knob will
control.
With the NOISE position selected, it controls volume of the White
Noise Generator. White Noise is useful for creating sound effects such
as Wind.
With the RING 1 * 2 position selected, it controls the volume of the
Ring Modulator. Ring Modulation is useful for creating harder Metallic
tones.
With the EXT position selected, it controls the volume of an external
audio signal connected to the INPUT socket on the K-Station’s rear
panel. This signal can be processed by the filter, envelopes and
effects.
An external audio signal may be a microphone, CD player, guitar etc.
With a little experimentation, quite effective and dramatic changes to
the sound can be produced : Filtering, wah-wah, gating, using the
Effects Section for adding reverb, chorus etc. Experiment !
Note: All three sound sources may be used simultaneously and if they
are, it may be necessary to reduce the Program Level dB in order to
avoid signal distortion (see page 26).
