5. VCOS
The top-panel modules VCO-1 and VCO-2 make up the oscillator section of JUP-8 V4. This is
where the sound starts. Here, you select the waveforms for each VCO, set their pitch, what
modulates their pitch (if anything), and how the two VCOs interact with each other.
5.1. VCOs 1 and 2
There are two oscillators to each voice. When the VOICE MODE is set to 16-note polyphony,
that's a total of 32 oscillators that may sound at one time. Each oscillator has its own tuning
control and can select from one of four different waveforms. By tuning them to various
frequencies, or by mixing different waveforms, the two oscillators allow you to quickly
obtain a rich variety of sounds simply by altering the top panel knobs, switches, and faders.
5.1.1. Differences between the oscillators
As tone generators, both VCOs perform similar functions, but you should be aware of some
differences in their capabilities:
VCO-1 is typically the "root" of the sound because its pitch can be set only to the
note being played or one of its octaves: its RANGE switch has only 4 positions.
VCO-2 is typically used as a harmonic of the sound, because it can be set to any
interval above or below the root note: its RANGE switch has 32 positions. It can
be fine-tuned plus or minus a semitone as well.
Both oscillators can generate sawtooth and rectangle waves. In addition, VCO-1
can generate a triangle wave or a square wave, and VCO-2 can generate a sine
wave or white noise.
VCO-2 has a LOW setting that allows it to be used as an additional Low
Frequency Oscillator.
VCO-1 has a CROSS fader that lets its frequency be modulated by VCO-2, either
as an LFO or cross modulator drastically affecting the sound spectra created by
VCO-1.
5.2. Source Mix control
The balance between the two VCOs is set by the SOURCE MIX knob in the center of the top
panel.
To hear only VCO-1: Turn SOURCE MIX full counterclockwise (LEFT)
To hear only VCO-2: Turn SOURCE MIX full clockwise (RIGHT)
To hear both VCOs equally: Double-click on SOURCE MIX (CENTERED)
Any setting in-between will increase one, and decrease the other as desired.
