In contrast to the other parameters of the Model oscillator, Resolution does not
reproduce a pre-defined real-world property of the physical model, but affects the
modelling process itself: higher values lead to an improved calculation resolution
which results in more overtones. Lower values reduce the precision of the calculations,
leading to fewer overtones and often to inharmonic spectra.
Filter Bypass Button
Between Oscillator 2 and the filter section you’ll find a signal flow switch that controls
the routing (Filter Bypass button). Repeated mouse clicks will send the signal to the
filter (Filter Bypass button turns red), or bypass the filter and send it directly to the EQ
section (Filter Bypass Switch remains gray). The direction of the arrow on the Filter
Bypass button illustrates the routing.
Note: The Filter Bypass button simply determines the signal flow. It doesn’t turn the
oscillator on or off. Use the oscillator On/Off button for this (see above).
The Ring Modulator
The ring modulator functions as its own sound source; its signal can bypass or be sent
into the filter, independent of Oscillators 1 and 2. Its volume can also be regulated.
Please note that both oscillators need to be switched on to use it.
The sound of the ring modulator is largely dependent on both of the oscillators, as it
modulates the output signals of both. Parameter changes, especially the tuning
relationships of each oscillator, have a direct effect on the sound of the ring modulator.
Note: The individual volumes of the oscillators have no effect on the process of ring
modulation.
The ring modulator doesn’t have an On/Off button like the oscillators. It is activated by
clicking directly on the Ring Mod label itself. When switched on, the label is red and
when off, it’s gray.
Note: As the ring modulator needs the signals of both oscillators to produce its output,
the ring modulator is muted when one of the oscillators is switched off. If you want to
hear the ring modulator’s signal in isolation (in order to better judge your settings),
temporarily set the volume of both oscillators to 0.
The slider adjusts the output volume of the ring modulator. Volume can be modulated
by the sources found in the Mod and Via menus. If sources are selected, small blue
(Mod) and green (Via) sliders appear beside the volume control. These allow control
over the effect of the Mod and Via modulation routing. The range affected by
parameter modulation is colored blue and green, and runs alongside the volume slider.
