Oscillators
Rotate the PWM knob fully clockwise. As the control is rotated, a double sawtooth wave is
generated. At this fully clockwise position the pitch will appear to double.
Select LFO 2 using the PW M select LEDs. Slowly rotate the PWM knob. Notice that there will
be some movement in the sound. Select a sawtooth LFO wave for LFO2 and rotate LFO2’s
SPEED knob - notice how the speed of the movement will change. Experiment with the above
controls until the desired sound is achieved.
MOD ENV Knob
Controls the amount of pitch modulation to an oscillator from the Mod Envelope. In the centre
position there is no effect on the oscillator's pitch; anticlockwise the effect is negative (i.e. the
pitch drops and then rises) and clockwise positive (the pitch rises and then falls).
LFO 1 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 regularly 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.
Some additional oscillator parameters can be found on the EXTRA page. These are described
on Pages 56 - 66.
