ORBIT 3
DOUBLE-SCROLL CHAOS OSCILLATOR
2
CONTROLS & CONNECTIONS
1 FREQUENCY RANGE SWITCH
This switch determines over which frequency
range Orbit 3 will operate: low frequency (VCLFO)
or audio frequency (VCO).
2 FREQUENCY KNOB
Although it may not always be apparent with
highly irregular chaotic signals, there is a
constant underlying oscillation frequency. This
drives the chaos and sets the rate at which the
signals evolve. It is controlled by this knob, with a
range of 22 Hz to 22 kHz in the audio frequency
mode.
In low frequency mode, the total range is
2.4 mHz (a period of 7 minutes) to 180 Hz, with
1 Hz when the knob is centred.
3 FREQUENCY MODULATION INPUT AND
KNOB
This input is used to modulate the frequency in
an exponential fashion. It includes a polariser
knob to set the modulation depth, with 0 in the
centre, standard +1 volt per octave maximum
and −1 volt per octave minimum in audio mode.
In low mode, the sensitivity is increased to
approximately 0.6 volt per octave.
3 DISTRIBUTION KNOB
The distribution knob manipulates Orbit 3’s
internal feedback path to change the nature of
the chaos generated by ‘widening’ the orbits.
When configured with a large distribution, the
oscillator will typically orbit closer to each of the
equilibrium points and spend more time around
it before switching to the other point.
4 DISTRIBUTION MODULATION INPUT AND
KNOB
The distribution parameter can be modulated
using this input, which also includes a polariser
knob. A modulation value of +5 V results in
maximum distribution.
