Oscillators
Oscillators
The Oscillators generate pitched waveforms (as described in
the Synthesis tutorial) and these are fed into the Mixer.
Most of the controls that determine the pitch and waveform of
the Oscillators, and how they react to modulation are in this
area.
Osc Select Switch
There are three independent Oscillators and each one can be
independently controlled by the switches and knobs in the
Oscillator area. To adjust the controls for Oscillator 1, select
position 1, to adjust Oscillator 2, select position 2 and to adjust
Oscillator 3, select position 3.
Octave Switch
Sets the basic pitch of Oscillator 1, 2 or 3 in Octave jumps. To
change the basic pitch of Oscillator 1, set the OSC SELECT
switch to position 1 and move the OCTAVE switch to position 1
NOTE: The
0
position corresponds to the pitch of 440Hz when
note A above middle C is played.
Waveform Switch
In the
position, the selected Oscillator’s waveform will
change to Sawtooth if the FUNCTION switch is set to NOR-
MAL or Sine if the FUNCTION switch is set to SHIFT.
In the
position, the selected Oscillators waveform will
change to Square if the FUNCTION switch is set to NORMAL
or Triangle if the FUNCTION switch is set to SHIFT.
Oscillator 1 - 2 Sync Switch
Synchronizes the waveform of Oscillator 2 to Oscillator 1. Each
time Oscillator 1 completes its cycle it resets the start cycle of
Oscillator 2. When listening to Oscillator 2 only, it has a dramat-
ic effect on the timbre of the sound. The easiest way to illus-
trate the effect is to create a sound using the Oscillator Sync.
Creating a sound using the Sync Effect
Select a factory preset basic sound - preset 499. Select OSC 1
and set its WAVEFORM to square - . Turn the OSC 1 &
2 knob in the MIXER section to fully clockwise to OSC 2. Select
OSC 2 in the Oscillator Section. Select OSC 2 WAVEFORM to
square - . Play a note and listen to the sound. It will be
a simple tone.
Apply a little MODE ENV depth by turning the MOD ENV
DEPTH knob slightly clockwise from centre. Adjust the MOD
ENV ATTACK and MOD ENV DECAY in the Envelopes section.
Listen to the sound, it will now rise and fall quickly at the begin
