Pre-Wired Connections
The panel silk-screening displays the various connections between modules that
have been pre-wired at the factory.
For example, in the VOLTAGE CONTROLLED FILTER/RESONATOR VCF section,
pre-wired connections from Voltage Controlled Oscillators 1, 2 and 3 into the VCF
block are indicated by the labeled boxes at the bottom of the section:
These labeled, pre-wired inputs correspond to sliders on the panel directly above
the label, which enables adjustment of the incoming signal strength.
The input jacks directly above each labeled box disconnects the pre-wired
connection whenever a 3.5 mm connector is placed into the jack,
as indicated by this graphic:
Voltage Controlled Oscillators (VCOs)
The Voltage Controlled Oscillators (VCOs) electronically generate repeating wave
signals, in a variety of waveforms that can then be shaped, combined and ltered
 INITIAL OSCILLATOR FREQUENCY – This slider chooses a VCO's coarse
operating frequency in four ranges for audio (10 Hz, 100 Hz, 1 kHz or 10
kHz) or four sub-audio frequency ranges (.03 Hz, .3 Hz, 3.0 Hz or 30 Hz)
when the VCO operates as a Low Frequency Oscillator (LFO). To choose
between audio and LFO modes, use the AUDIO/LF sliding switch in the
lower left of each VCO.
 FINE TUNE – Use this slider to tune the frequency chosen by the INITIAL
OSCILLATOR FREQUENCY slider up or down as needed to nd the precise
frequency you need.
 PULSE WIDTH – Use this slider to set a default width for the waveform.
 SYNC ON/OFF – Use these sliding switches to lock VCO2 and/or VCO3 with
VCO1 so that the synced oscillators act as a single large oscillator that
follows the frequency of VCO1 to produce complex sounds.
 OUTPUTS – These output jacks allow you to send out either audio or
LFO signals from the VCOs via cables with 3.5 mm connectors. The type
of waveform is indicated by the silk-screening associated with the jacks
(sawtooth, pulse, sine, triangle, and so on, depending on the speci c VCO
in use). The PULSE outputs can also be used to mix in signals from the
lower LFO section (VCO1), the NOISE GENERATOR section (VCO2), or the
ADSR ENVELOPE GENERATOR (VCO3) to produce a composite output signal.
 AUDIO/LF (KYBD ON/OFF) – This sliding switch chooses between audio
and low (LFO) frequencies for adjustment with the INITIAL OSCILLATOR
FREQUENCY, FINE TUNE and PULSE WIDTH sliders. When using the VCO as
a Low Frequency Oscillator, keyboard control is automatically disabled. In
the AUDIO position, keyboard control is enabled.
 FM CONTROL – Use these inputs to route in external control voltage
signals via cables with 3.5 mm connectors. Placing a connector into one of
these jacks disconnects the corresponding pre-wired connection indicated
directly below the jack.
 PWM – Use this input when you want to route in external control voltages
to control the pulse width in place of the PULSE WIDTH slider.
