4 HFO (high frequency
oscillator) knob.
Master sync oscillator. Turn the knob
to set master pitch. The VCO will sync to
this pitch creating harmonic steps and
wave shaping effects when adjusted.
5 MODE switches.
Change the oscillator wave shape
by setting both mode switches.
AI. = simple tone
BI. = complex tone
AII. = noisy tone
BII. = digital noise
Each mode reacts differently to the
master sync oscillator and the data
modulation setting.
6 DATA MODULATION
switch.
Apply the LFO to a wave shape
processor. Speed of modulation is set
with the LFO and CLK OUT switch
(On right side panel). The effect differs
in each mode.
AI. = pitch modulation
BI. = wave shape inversion
AII. = slight wave shape randomization
BII. = noise randomization
7 LFO (low frequency
oscillator) knob.
Controls the rate of sound modulation
when the data mod switch is on
TECH NOTE Each oscillator is based on a common schmitt trigger (inverter), resistor, capacitor
architecture. The bend socket is connected to the input and output of the schmitt trigger.
Connecting resistors(like the LDR) to these points will change the pitch of the oscillators.
Lots of other effects can be achieved by connecting other components and signals to these sockets.
(and more...discussed later). The LFO
range is set with the LFO RATE switch.
8 BEND sockets
[input/output].
Plug light sensors (included) into any
of the bend sockets to control each
oscillator with light. Plug in other stuff.
