Ultrabeat sound sources
Ultrabeat oscillator overview
Ultrabeat oscillators are used to generate waveforms. oscillator 2 can use a sample in place of a
waveform. The signal of one or both oscillators is then sent to other portions of the synthesizer
engine for shaping, processing, or manipulation.
••
Oscillator 1 can be frequency-modulated by oscillator 2, for FM synthesis sounds.
••
Oscillator 2 can be ring-modulated with oscillator 1.
••
Oscillator 2 can use an audio file (a sample), in place of a synthetic waveform. The sample is
output as the oscillator 2 signal.
Other sound sources include a separate noise generator and ring modulator that can produce
additional signals to those generated by the oscillators. See Ultrabeat ring modulator on
page 349 and Ultrabeat noise generator on page 349.
Common oscillator parameters
These parameters are available to both oscillators.
Pitch field
Pitch slider
Volume knob
Mod and “via” menus
(for volume)
Signal Flow button
Mod and “via” menus
(for pitch)
••
Oscillator on/off button: Click the button (at the top left of oscillator 1 or bottom left of
oscillator 2) to turn each oscillator on or off independently.
••
Volume knob: Sets the level of oscillator 1 or 2. Volume can be modulated by the sources found
in the mod and pop-up menus.
••
Pitch slider and field: Drag to set the oscillator pitch in semitone steps. Press Shift to adjust the
pitch in cent intervals (1 cent = 1/100th semitone). Pitch can be modulated by the sources
found in the mod and via pop-up menus.
••
Signal Flow button: Click to route the signal of the associated oscillator through the filter, or
directly to the EQ (in the Output) section. When turned on, the button is lit and an arrow
indicates the direction of the signal flow.
••
mod and via pop-up menus: Determine the modulation sources for oscillator pitch and level.
