OSCILLATOR 1 (Continued)
PITCH IN
A control signal connected to this input will modulate the Pitch (Frequency) of
Oscillator 1. This input voltage is added to the voltage from the note played on
the keyboard.
PWM IN
A control signal connected to this input will modulate the pulse width of
the Square or Narrow Pulse waveform selected by Oscillator 1. Pulse Width
Modulation (PWM) varies the duty cycle, or pulse width of a wave, and thereby
changes its harmonic content. Among other things, PWM is often used to
mimic the sound of ensembled strings and to thicken bass sounds.
OSCILLATOR 2
OCTAVE
This four-position switch is used to select the fundamental Octave setting for
Oscillator 2. The choices are 16’, 8’, 4’, and 2.
FREQUENCY
This knob detunes Oscillator 2 from Oscillator 1 over a range of +/- 7
semi-tones. The center position (12 O’clock) puts Oscillator 2 in unison
with Oscillator 1. Increasing the value raises the pitch, decreasing the value
lowers the pitch. When the SYNC button is lit, the pitch of Oscillator 2 is
locked to Oscillator 1; in this case, changing the Frequency value will vary
the degree of the Sync effect and effect harmonics. The range of the
FREQUENCY knob is also greatly increased.
NOTE: The range of the FREQUENCY knob can be specied in the
Global Settings.
WAVEFORM
This four-position knob is used to select the Waveform setting for
Oscillator 2. The choices are Triangle, Saw, Square, and Narrow Pulse.
