Common oscillator parameters
These parameters are available to both oscillators.
• 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: Set 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. See Logic Pro Ultrabeat modulation overview.
Switch between Ultrabeat oscillator synthesis modes
Oscillator1 can switch among three synthesis engine types:phase oscillator, fm, and side
chain (external audio input). Each mode provides different parameters and features.
Oscillator2 can switch among three synthesis engine types:phase oscillator, sample, and
model. Each mode offers different parameters and features.
• In Logic Pro, click a button on the upper edge of oscillator1 to select a mode
(synthesizer engine).
