Volume
Each oscillator features a volume control. This allows you to mix the
levels of the three oscillators into the filter.
Rather than limit the Trigon-6’s outputs to keep the instrument from clipping, we
allow you to adjust levels at various points in its signal path. This gives you the option to
“overload” things in interesting ways, if you wish to do so. If not, try reducing the levels of
the oscillators using the
volume
controls.
volume
at 50% results in relatively clean signals
into the filter.
Feedback<>Drive
The
fdbk
<>
drive
knob is bidirectional and controls two separate param-
eters.
When the knob is turned clockwise,
drive
affects the amount of filter
saturation by increasing the oscillators’ overall output.
When turned counter-clockwise,
feedback
can introduce a range of tones
from harmonic to chaotic by feeding the Trigon-6’s voice card outputs
back into the filter stage. This allows a feedback path for each voice.
Noise
Sets the output level of the white noise generator.
Filter
Filters take the basic, raw sound of the oscillators and noise generator
and subtract frequencies, changing the harmonic content and character of
their sound. This change can be varied over time using the Filter Enve-
lope
to produce more dynamic, animated timbres.
In simple terms, a lowpass filter cuts high frequencies. The Trigon-6’s
2/4-pole switchable lowpass filter allows for a wide range of sonic possi
-
bilities, with a classic sound. Just like in historic 4-pole lowpass filter
circuits, when
resonance
is increased some bass is lost from the signal.
