OSCILLATORS
Dominion I utilizes three voltage controlled oscillators
(VCO) with almost equal functions. Differences are to be
found for the Tune controls and ring modulation. All
described functions are valid likewise for VCO1, VCO2
and VCO3.
Use the four-stage selector Wave to choose the
waveform. Available choices are triangle, saw tooth,
square and ring modulation resp. XOR. When set to
Ring/XOR, the oscillators modulate each other as follows:
VCO1 – VCO1 <> VCO2 (resp. external signals RM X/Y In)
VCO2 – VCO2 <> VCO3
VCO3 – VCO3 <> VCO1
Oscillator 1 offers an analogue ring modulator, while
oscillators 2 and 3 each utilize a digital ring modulator
with so called XOR wiring which offers a rough sounding
character.
To be able to hear the ring modulation of VCO1, you
have to turn up RM Y In in the mixer section. In alternative
to VCO2 and/or VCO1, external audio signals can be fed
into the connectors RM X In and RM Y In on the unit's top
panel (see page 32).
The Tune control for VCO1 sets the general tuning for all
three oscillators. The available range is approx. ±6 semi
tones.
The Tune controls for VCO2 and VCO3 set the tuning for
the respective oscillators. The range is approx. ±13 semi
