Chapter 23 Ultrabeat 309
The Synthesizer Parameters
In this section, you’ll find a description of the individual parameters found in Ultrabeat’s
synthesizer section. A discussion of the signal flow can be found in “The Signal Flow”
section, on page 306.
The Sound Sources
A drum voice in Ultrabeat has four sound sources: two multi-synthesis capable
oscillators, a noise generator and a ring modulator.
Oscillator 1
To use Oscillator 1, you need to first turn it on. This can be done with the On/Off button
in the upper left corner of the Oscillator 1 section. When in an active state, the button
is red.
Note: When you program a drum sound, you can turn the individual sound sources on
or off with the corresponding On/Off buttons. You can also listen to the individual
components of the sound separately this way, and remove them from the patch if
necessary.
The volume of Oscillator 1 is controlled by the Volume knob on the right edge of the
Oscillator 1 section.
Volume can be modulated by the sources found in the Mod and Via menus. If a Mod
source is activated, the effect it has on Volume is set by the (Mod) ring that surrounds
the knob. If a Via source is activated, its effect can be set by moving the slider that
appears on the Mod ring. Colored areas between the Volume knob and its surrounding
ring clearly show the values of the Mod modulation (blue) and the Via modulation
(green), compared with the mean Volume value (red).
If neither a Mod or Via source is selected (both set to Off), the Mod ring, its slider and
the colored areas remain hidden.
