Chapter 24 Ultrabeat 355
The pitch value is displayed to the left of the slider. You can change the displayed value
by click-holding directly on the value field, and moving the mouse vertically.
Pitch can also be modulated by the sources found in the Mod and Via menus.
You’ll find a signal flow switch between each of the oscillators and the Filter section
that controls routing (filter bypass button). Repeated mouse clicks will send the signal
from the respective oscillator to the filter (filter bypass button turns red), or will bypass
the filter and send it directly to the EQ section (filter bypass button 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’s On/Off button to activate it (see above).
Unique Properties of Oscillator 1
Oscillator 1 can be switched between three different types of synthesis engines: Phase
Oscillator, FM, and Side Chain (external audio input). This can be done by clicking the
appropriately labeled buttons at the upper edge of the Oscillator 1 section.
Phase Oscillator
The waveform of the phase oscillator can be twisted with the Slope, Saturation, and
Asymmetry parameters, and shaped into almost any basic synthesizer waveform. The
effects of these three parameters are graphically illustrated in the waveform display
within the Oscillator section. Setting all three parameters to zero values will cause the
oscillator to produce a sine wave.
 Slope: Determines the slope or steepness of the waveform. The higher the Slope
value, the steeper the waveform. The resulting sound takes on an increasingly nasal
character as the incline becomes more vertical.
