❸Frequency
This knob controls the frequency (rate) of the built in triangle oscillator. Fully turned to
the left it oscillates slowly like an LFO, but as you turn the knob clockwise, you’ll quickly
get into audio range. The oscillator is primarily used at high frequencies to create
frequency sideband effects while modulating the carrier signal. If you want a slower
movement you can plug in an external LFO into the Y input.
Note! When there is a patch cable inserted in the Y Input, the frequency control knob is
bypassed. This knob has no other function than setting the speed of the oscillator.
❹RM Mode
RM Mode switch (Ring Modulator Modes)
1: Four-quadrant multiplier mode. Modulation of the carrier signal with offset control.
A good start if you want to make typical bell-like tones.
2: A single stage soft folding circuit that bends the waveform and thereby adds extra
harmonics to the carrier signal. Increase the level of X input to make the waveform fold
into itself. Offset Mod input can be used to animate the folded signal. For example,
use a slowly moving LFO and experiment with the level knob.
3: A hard folding circuit that generates a unique center aligned pwm-like waveform
which can be animated using the built-in oscillator or an external CV source, for
example an envelope generator. For example, insert a slowly moving LFO into the
Offset Mod input to try it out further.
❺Offset Modulation
Please note, an external CV signal or audio waveform is required here!
This input differs from the other two in that any signal used here will have different
effects on Clang's two outputs. The basic function is to offset the modulation signal
from the carrier in order to produce more complex sounds. The left output provides the
multiplied signal which in turn is routed via an VCA connected to the right output.
This means; any signal in this input will have effect on both the ring modulated sound
and the VCA.
A great way to learn how it works is therefore to connect an envelope generator
and observe how the signal is processed though both outputs. Turning the knob fully to
the left will attenuate the signal, leaving the modulating signal untouched, the right
output will behave like any linear VCA would do. Also try to use this input with audio
signals to achieve even more complex sounds. Try experimenting with different
waveforms at different frequencies.
