VCO 1 and VCO 2
Both Voltage Controlled Oscillators (VCOs) are the SUNSYN’s most important sound
sources. They’re made up of discrete analogue circuitry. Essentially, they produce audio signals
with different waveforms. The different waveforms contain different harmonics and therefore
have different sonic characteristics. The
frequency of the VCO’s pulse width can be
voltage controlled with the use of
modulation inputs (more on this later on).
The VCO’s are principally identical. The
following control elements are available:
(Range)
defines the octave setting from
‘32 to ‘2. The ‘16 and 4’ buttons have dual
functions. When the ‘16 LED flashes, the
octave setting is ‘32. When the ‘4 LED
flashes, the octave setting is ‘2. Try it!
You can use the
(Semitones)
-knob to tune VCO 2 against VCO 1 in semitones. The
transposition range is 1 octave.
The
(Cents)
-knob can be used to fine-tune VCO 2 against VCO 1. The range is one
semitone.
Although the user interface might suggest that
Semitones
and
Cents
affect VCO 1, they only
affect VCO 2. VCO 2 is always tuned against VCO 1.
The
(Waveform)
-buttons define the
waveform that a VCO produces. You
can alternatively use either Saw Wave
B
or Pulse/Square Wave
D
.
The
(Pulsewidth)
-knob sets the Pulsewidth of the Pulse signal.
A parameter value of
< 068 >
means a symetric Square signal.
Reducing the value to
< 000 >
reduces the pulsewidth.
Values to
< 127 >
wides the pulses.
(Level)
defines the output level of the oscillator signals. This
parameter only affects the hardwired signal that goes into the
filter. It does not affect the signal that may be used in a Routing
Element (more on this later on). The level range is calibrated in
such a way that it is possible to (intentionally) distort the signal.
